Ok, I’ll try that next.
It probably is me doing something wrong, it was still drivable before I tried bleeding it again

It could also be an issue with the clutch plate if the pedals really hard

We went to Mallory Park yesterday for a Javelin track day. We had not been to Mallory Park before so for £179 (plus an additional driver) we thought it would be worth a go.
We travelled up the night before and managed to use the journey and some extra driving miles to bed in the new 330mm Godspeed discs. The RPX pads had left a smearing deposits on the front discs which didn't look good. When we got to the circuit we put the DS1.11 pads in and blocked up the brake ducts so that we could bed in the pads. After the sighting laps and a some laps with deliberate heaving breaking the new brake set up was bedded in. The deposits left by the RPX pads were gone and the discs were showing signs of going through some heat cycles.
We came back in to the paddock, took the tape off of the brake ducts and did the first proper session. The Clio was flying around the four corners of the track, but we were still suffering with clutch drag. We had attempted to bleed the clutch in the week and had the tools to bleed the clutch at Mallory Park.
I went out for the second proper session. Most of the course could be done in fourth gear apart from the hairpin, although the car was hitting the limiter just before the first and second corners.
We came back to the paddock and decided to bleed the clutch. That was the end of our day. We think that the slave let go at this stage and we could not get enough pressure to engage the clutch. Whenever we tried to bleed the clutch the bleed clip came off. Despite the really helpful remote assistance from Alex at AW Motorworks the slave seals were knackered. We managed to get the car moved from the paddock to outside the track gates and discovered we were missing an O ring. Despite managing to get an O ring from a garage on the site we could not get the clutch pedal back. Each time we went through the bleed procedure the pedal would go really stiff and then just "push"off the clip on the valve.
We conceded defeat about 3pm and then organised a man with a trailer to get us home. This was the 31st track day for the Clio and it is only the second time it did not drive home under it’s own power.
We will diagnose the problem, probably fit a new slave and get the Clio ready for Blyton Park in 12th April 2025.

We are working on the basis that there is something wrong with the clutch system that is causing the gearbox problems. The gearbox has been rebuilt so it should be healthy internally. The clutch and slave were not replaced when we refurbed the gearbox so they are potential problems.
At Mallory Park we had two problems when bleeding the clutch. The first problem was that when we opened the bleed valve, bled the clutch, and then closed the bleed valve brake fluid was still dribbling out of the bleed nipple. I think that this was due to us missing an O ring off of the end of the slave cylinder. The second problem was that after adding in a second O ring (which might not have been the perfect size) when we tried to bleed the clutch we would open the bleed valve by moving the clip but when we pressed on the clutch pedal it would go down a little bit and then there was a lot of resistance. When you pushed past the resistance with force (using as little force as possible but having to give it some force to make the pedal move) the bleed clip would fly off and brake fluid would then shoot out.
Slave cylinders are not too expensive so we will get another slave and the resident mechanic @EthanMenace can pull the box out and replace the slave.
Does anyone know what the part number is for the hose the connects to the slave cylinder? That is the hose that has the bleed clip and bleed nipple and would slide on where the red arrow is below. I have had a look on Dialogys but cannot find it.
You can see from this video of Ethan's first session, well his only session, that gear changes were difficult up to third and fourth and down from fourth and third.
I have said this before but we made no effort to use fifth gear at Mallory Park as it was easier just to drive up to the limiter and stay in fourth gear.
The car is now irritating me as the gearbox seems to be the only part really holding it back this year. We have to be patient and wait for the car to be able to change gear and that is interrupting the flow and slowing us down on track days.
I think that I now have our TPMS system up and running. I am good with technology but trying to work out how to configure sensors in a CAN bus system is beyond me. After getting some external help the sensors were providing sensible and realistic readings on Friday. This is what the TPMS readings were at the start of a session. For context we had been out for about 3 laps to bed in some brake pads, came back in and took off the tape from the fog light brake ducts and then headed straight out. Mallory Park is a clockwise circuit with a large sweeping right hander after the start/finish straight. The front left tyre was showing more wear than the front right tyre after our day ended so I would expect the tyre pressure to go up higher in the front left tyre.
This is the pressure readings after about 15 laps on track during the same session. I am suspicious of the rear readings as they stayed constant thought the session.
I thought that we would kill off the track tyres at Mallory Park but as we did not use the tyres much they are still okay. I have had a new set of Direzzas delivered by Tegiwa.
Tegiwa have managed to deliver three 215 wide tyres and 1 225 wide tyre!

I didn’t realise you were getting resistance in the pedal.
Simmo’s had that before and it was an issue with the clutch plate, which in turn killed the slave.

We got the resistance in the pedal at the end when we were bleeding it, and not before when we were driving it.
This may be a silly question but is the clutch plate all part of a clutch that you can swap out rather than another piece of kit?

No no, the plate (also can be called the cover) generally comes with the clutch.
I’m sure it was one of the rivets which had gone on Simmo’s plate which was stopping the clutch from disengaging properly.

We have purchased a new genuine slave from FrogJam.
I am really hoping that this solves our gearbox issues.

@EthanMenace whipped the gearbox out today and put in the new slave cylinder.
The old slave was not looking very healthy. The outer rubber cover was torn and after we sent a photo to Alex from AW Motorworks he suggested that the slave could have over extended itself.
The gearbox was out quickly and went back in all within a half a day.
This is the old slave from another angle.
Ethan found part an O ring that went missing at Mallory Park on top of the gearbox.
The gearbox oil that came out has definitely got some metal in it. There are some shiny particles in the bottom of the bucket that I looked in. We did Donington when the gears were still catching. At Mallory we did try to get the car moving when the clutch had failed by bump starting it and trying to flat shift.
I have ordered some more Redline 75w80 gearbox oil and when that arrives in the week we can fill up the box with oil, bleed the clutch properly and then see if the box is any better.
At least if we have knackered the box we can take it out on the drive!
After putting the box back on Alex did suggest that it would have been a good idea to check the clutch. Oh well, we are all wiser in hindsight.

I was just about to say did you check the clutch and cover!!!!
I guess at least there were no loose parts inside the housing. That’s usually a good indication if there’s an issue with it.

I did a brief check to see if there were any loose bolts or rivets missing from the plate but my process was essentially: the clutch is still here.

We went to Blyton Park for a track day on Saturday 12th April 2025, Blyton Park is a track that have not been to before.
I was not expecting much from Blyton as the track day was cheap at £169 plus an additional driver, videos on line did not look very exciting as the track has no elevation, and I was expecting the gearbox to be "difficult". The day did not start very well when it took three attempts to get some petrol and had to settle for some 97 unleaded.
But, it was actually a very good day. The weather was perfect for a track day, bright sunshine and about 20 degrees. The cars on track were generally well behaved apart from a few race cars that were getting some track practice in. @Tarticmonkey and some of his friends were also at Blyton - they did behave.
The day started well as after a few sessions the gearbox was behaving reasonably well. It was changing gear and not crunching very much, it was usable and didn't ruin the day. The slave cylinder had been replaced and had been bled several times. You still had to be patient with gear changes so it still requires some fettling to make it perfect again. As Mallory Park had not been very successful a few weeks ago we had not had a good opportunity to test out the new brake set up.
After a few sessions I decided that Bylton was actually quite a fun track. Although it is completely flat it had a chicane (The Wiggler) that showed us that the Megane brake set up as working really well and a set of esses (Bunga Bunga to Port Froid and on to Ushers) that if you had big enough balls you could do flat.
@EthanMenace did a session around 11am where he and @Tarticmonkey chased/followed each other where Callum showed his special technique of getting through two sausage kerbs at The Up by riding them launching his car on to two wheels after each kerb. There was also a session with a Twingo with a Clio engine who was very complementary about Ethan's driving.
When we got to lunch time we went in search of more petrol and when we returned we decided to take the spacers off the rear axle. We should have done this earlier as it showed that the car was more capable in tighter corners and really improved the handling.
At the start of the day Ethan had put in a lap time of 1m 18s and I had managed a 1m 21s. By the afternoon lap times were improving as we got more familiar with the track and I felt more comfortable flinging the Clio around.
During the afternoon Ethan managed to nudge one of the course markers at about 90 mph. It wasn't a tyre stack and was more like a plastic bale of hay. Fortunately there does not appear to be any damage and the marks should come out with a bit of T Cut or a good polish.
By the end of the day I managed to get a 1m 17s time and had finally had the confidence to drive the esses flat. Ethan finished the day with a respectable 1m 13s time. The car finished the day in one piece although it is filthy and covered in dead flies. The Clio has returned to its usual standard of getting through a track day without falling apart. Nathan Driver was also a Blyton in his Clio but it suffered a slave cylinder failure after a few laps.
The brakes worked really well. It was really clear that the Clio could brake really late compared to similar cars. We had fitted a new set of Direzzas on to the track wheels just before Blyton and the combination of Megane brakes and Direzzas worked really well.
I did have the GoPros running all day and have got lots of footage. The exposure settings weren't set correctly and the bright sunshine has caused the footage to look a bit crap. I will see if I can adjust the exposure and make it look a bit better.
I did think that we would do a day at Blyton Park and probably not go back but I would definitely go back to Blyton again.
We are waiting for some track door cards to be delivered. We have a driver's side footplate and have spoken to KIS Motorsport and they are going to make a passenger side footplate to match the aluminium finish of the PMS one we already have. The interior of the car will probably stay in until we come back from the Nurburgring in July. I have also managed to find someone to make some new door sill plates. Apart from stripping the interior we don't have any more plans to modify the Clio at the moment - but as everyone knows we are likely to find something to spend money on at some point in the near future.

It was a mega day! Was good seeing you and Ethan again.
Definitely up for making a trip down south at some point to meet up again at a trackday too!

I found that a wider front and a narrow rear with no spacers on the back is mega as well. I removed my rear spacers a few years ago and never put them back on. The car looks better with them on but at this point I'm more worried about speed than looks lol
I had heard that rentune used to modify the rear beam to make it even narrower, I don't know how true that is as I heard that information second hand.
