awkward with diff carrier in place but possible need car jacked up high as you can remove lower plate on carrier for better acces remove hand brake cable from callipers release lock tab remove the mounting bolts and the fork feed calliper round brake disc towards rear of carrier on bench note correct fitted position of pads remove nuts holding each pad clean mounting faces well if this not done new pd can be damaged fit and secure new pads unwind adjuster bolt operate calliper lever to check adjuster working should hear it click if ok refit io car guide in poition locate in position a taper gound on to bolt helps as easy to miss hole in calliper when happy it correct gently remove bolts fit fork and tab secure bolts engage fork lugs in calliper arms operate calliper lever by hand till freeplay is taken up pads now in correct position do other side refit cable and lower plate good luck

some rev limitors have a reset.check owners manual for location

The Renault clio should be easy,.jack up one wheel and remove the wheel and see what if any special tools will be needed. most have two bolts that hold the caliper to the back plate. The caliper hold the pads. Some of thes bolts are Allen head, some are Torq head, all are metric. some are held in with clips, remove the retaining pins and pull the clips out and the caliper comes out the front. Press the piston back into the caliper, so the new pads will fit over the rotor.

Your code is 4732

One, take your brake fluid reservoir cap off.
Two, use a thin piece of wood to help you compress the piston on the caliper....do it slow. This way, you don't create a lot of pressure to the reservoir and it won't overflow.
Three, these are the steps to removing and replacing the pads for the rear. It does mention a special tool....but you can use a c-clamp for the same purpose:

Rear To Remove:

1. Check the brake fluid level in the brake master cylinder reservoir.
2. If required, remove the fluid until the brake master cylinder reservoir is half full. CAUTION
   Care must be taken when servicing rear brake components without disconnecting the parking brake cable from the brake caliper lever.
   
3. Remove the disc brake caliper. Support the caliper with mechanic's wire. CAUTION
   When the brake pads are separated from the brake caliper, new brake pads must be installed. The brake pads are one-time use only.
   
4. Remove and discard the brake pads and spring clips from the brake caliper anchor plate. NOTE: Do not remove the anchor plate guide pins. The guide pins are press fit to the brake caliper anchor plate. If the guide pins are damaged a new anchor plate must be installed.
   
5. Inspect the brake caliper anchor plate assembly.
6. Check the guide pins and boots for binding or damage.
7. Install a new brake caliper anchor plate if it is worn or damaged.

To Install:
NOTE: The left caliper piston turns clockwise and the right caliper piston turns counterclockwise.

1. Using the special tool, turn and compress the brake caliper piston into the cylinder.
2. Clean the residual adhesive from the brake caliper fingers and pistons using the specified brake parts cleaner. CAUTION
   Do not allow grease, oil, brake fluid or other contaminants to contact the brake pad or caliper mating surface. Do not install contaminated pads.
   NOTE: Install all the new hardware supplied with brake pad kit.
   
3. Install the new spring clips and brake pads.
4. Position the brake caliper and install the 2 bolts. Tighten caliper bolts to 23 ft-lbs (31 Nm).
5. If necessary, fill the brake master cylinder reservoir with clean brake fluid.
6. With the engine running, apply pressure on the brake pedal to seat the brake pads.
7. Test the brakes for normal operation.

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?

change the control switch ,but newer models use a module and it could be this module playing up it controls the a/c and heating .if its the module then iam sure its dealer only as its a renault and no doubt will require reprogramming

You do not use the buttons.

You have to use the Steering Wheel remote Control
