Clio 200 RS - Brembo Caliper - OSF Hot?

[Graham200]

I have experienced a few braking issues with the car since I bought it two years ago. After a trackway at Knockhill last week, I fitted 4 new Godspeed G hook discs.

On the way home last night, I was braking gently (as per the running in guidance) but noticed the OSF disc was much hotter than the NSF, when I arrived home.

I bought second hand callipers last year and thought this would eliminate it - had a braking imbalance last year. Also fitted new HEL brake lines at the same time.

Am about to buy new front callipers, before I do, I wondered whether any other factors could be at play i.e. Master Cylinder etc? I don't want to fry my new discs :-(

(picture was taken yesterday before new discs/pads were fitted)

Be worth stripping the brakes, cleaning the sliding faces, and applying a little copper grease to the ends of the pads first.

I gave the calipers a decent clean up. Put copper slip on the edges of the pad (where the contact the calliper) and cera tec over the back of the pad. Also copper slip on the retaining pins.

Would you put copper slip / cera tec anywhere else?

remove pads and check all 8 pistons are free to move - may have to get someone to pump the pedal to push the pistons out abit make sure they "feel" the same when pushing back in - there could be a "tight" piston/seal on the caliper...

Thanks. Will give that a go. Should I be able to push the pistons back in by hand? Or lever them with a screwdriver?

should be able to move by hand within reason once pads out of way - move one and the others usually move out - use a flat tool/bar rather than screw driver as it will keep the force spread over a greater area of the piston

Ok. Will do that and see if they all require equal pressure. [emoji106]
