    It’s out, it’s finger tight that’s the problem, the threads in the caliper are destroyed and it’s just sitting there loose and can’t be tightened

    I’ve taken both rear calipers off this morning, if I’m getting one done I might as well get both done. It’s only money right :think: Here’s the offending bleed nipple that some utter cretin has just mangled: Pad wear comparison between sides. I do wonder if the brake locking at Cadwell...

    Also removed the dead Godspeed discs and dead DS1.11 pads. Fitted new Brembo discs and new DS1.11 pads. Gave the pins and good clean and a bit of copper slip. On a roll, I went to flush the brake fluid through, only to find that whatever ham fisted idiot was there before (wasn’t me, before...

    Short version - New coil pack needed. Long version - car was running fine at Cadwell Park, left it on the trailer overnight then took it for a pre-Germany service. On starting it up, it was running rough again. Plugged in and it gave the following: P0530 I though we can probably ignore as...

    Running on 2 cylinders P0638

    Strangely I have this problem again, not quite as pronounced, but definitely running weak on Cyl 2 & 3. I do wonder whether there is a micro-break somewhere along the harness that serves 2 & 3 and I just got lucky replacing the throttle body.

    Load sensing valve?

    It's getting a full RBF660 flush this week anyhow. I'll ask him to take apart the rears and give them a clean.

    Cadwell Park 8th April 2024 First proper track day of the year after the failed attempt at Donington in March. Between then I'd replaced all four spark plugs and the car was running nicely. Trailered it over the night before and stayed in Kenwick Park which was about 10 minutes from the...

    Load sensing valve?

    Doesn’t look that bad actually, definitely the unloaded rear corner. Maybe I’ll just live with it.

    The saga continues - P0530

    After a faultless day on track yesterday, the car sat overnight on the trailer in the rain. Starting it this morning it was lumpy and sounded like it was running on three cylinders. Water was pooling around cylinder 4 coil pack (classic Renault leaks) so thought it might be that. However drying...

    Load sensing valve?

    Does the Clio 197/200 have a load sensing valve to distribute braking force front to rear? I was getting a lot of rear lockups on track yesterday which I've never had before, and trying to work out why. Thanks

    Print out of what? They need to be flexible, is that even possible?

    I noticed when I was doing the brake cooling that the dust boots on the SuperPro anti-rotation links were cracking and perishing. I'm replacing these before they split and lose the grease inside. I called up SuperPro (Octane Distribution Ltd) to enquire about spares. They are £6+VAT each...
