Renault clio 2ltr sport back brakes

How many cylinders

The rear callipers contain the hand brake mechanism, they need to be wound back to install the new pads, have a look in your local car part suppliers/accessory shop, the correct tool is about £10 or so. You can wind it back with a screw driver and a "G" clamp, they need to be wound clockwise when you look at the piston through the calliper frame, use a large screwdriver in the notches in the piston to turn it, sometimes the screwdriver needs to be sideways, this will be fiddly as you can usually onlt turn 1/4 of a turn at a time, squeeze the piston back with the clamp after a turn or so and repeat untill the piston is back enough to allow the pads in.

That is your trust bearing in your clutch assembly, its a cheap part but involves basically a clutch change to sort out, you can either live with it till the clutch fails or depending on how long its been since it was last changed, bite the bullet and get a whole new clutch fitted.

possible causes , part siezed brake wheel cylinder or hand brake cable not returning correctly - first back off hand brake cable then check rotation of wheel - either way it will need stripping down checking - but not too expensive - andy - need to know more just ask

Most of your braking occurs at the front of the car, anyways, but you need to get those rear brakes checked...

If you have a split (front-rear) master cylinder, check that. Did the fluid level drop enough at any time such that the system may have "sucked air" into the rear system only?

You mean brake load sensor.
Usually by the back axle. It spreads the braking evenly between front and rear brakes.
When did you last change the brake fluid. It is hygroscopic(attracts water).
When it is contaminated with water it makes your brakes fade very quickly.

are you tightening it up with the car on the ground or jacked up ?
