We remove the caliper and brake disc for repair or replacement
You will need; keys "for 11", "for 18".
Remove the wheel from the side of the caliper to be replaced.
Loosen the end of the brake hose.
Substitute a container to drain the remaining brake fluid from the hose and cylinder.
Remove the two bolts securing the shoe guide to the steering knuckle
Remove the caliper from the steering knuckle and disconnect it from the brake hose by unscrewing the caliper from the hose end.
Install the caliper in the reverse order of removal.
Tighten the end of the brake hose completely until the caliper is installed on the steering knuckle.
When installing the caliper, make sure that the hose is not twisted.
Before installing the caliper mounting bolts, apply an anaerobic threadlocker to the threads of the steering knuckle.
After installation, restore the brake fluid level in the reservoir of the main brake cylinder and bleed the air from the hydraulic brake actuator (see "Replacing Renault Logan brake fluid").
Replacing the brake disc
If there are scuffs, deep scratches and other defects on the working surface of the disc that increase pad wear and reduce braking efficiency, as well as in case of increased lateral runout of the disc, causing vibration during braking, replace the disc.
In specialized workshops, such a disc can be machined and polished on both sides to the same depth, but after processing, the thickness of the disc must not be less than the minimum allowable.
The minimum allowable brake disc thickness is 10.6 mm.
If one of the discs is less than the specified thickness, replace both discs.
When replacing brake discs, be sure to replace the brake pads with a new set.
You will need the T0RX T30 key.
Remove the wheel from the side of the rim you are replacing.
Remove the caliper assembly without disconnecting the brake hose, and secure with wire without twisting or pulling the hose
Remove the two screws securing the brake disc to the front hub and remove the brake disc from the front wheel hub.
Remove the right brake disc in the same way.
Install the parts in the reverse order of removal.
Before installing the disc, carefully clean the mating surfaces of the hub and disc from rust and scale, as even the smallest particle sandwiched between the mating surfaces will cause the disc to beat and vibrate when braking.
If you are installing an old disc, use a file to remove the edges on the working surfaces of the disc that have formed on both sides as a result of wear.
