Survey, removal and installation of a disk of the forward brake mechanism

If one of disks demands replacement, replace BOTH disks simultaneously to provide equal and effective braking. It is recommended to replace also Pads.


1. Cock a manual brake, then поддомкратьте a forward part of the car and reliably establish it on axial props. Remove a forward wheel.
2. Slowly rotating a brake disk, attentively examine it from both parties. If to an inside the best access is required, remove brake Pads. Presence of superficial scratches in the area captured brake колодками, is quite admissible - the surface can be ground an emery paper. If in this area deep grooves are found out, the disk demands replacement.

3. Presence on periphery of a disk of the ledge formed by a rust or the stuck dust, is quite admissible. This consolidation is possible соскрести. If, however, difference of a thickness was generated because of deterioration of the area captured колодками, measure a thickness of a disk by means of a micrometer (address to an accompanying illustration). Execute gaugings in several places, in contact with колодками areas and out of it. If at least one of measurements equally or less than the minimum thickness specified in Specifications, replace a disk.

4. If the disk is presumably deformed, check up it on palpation by means of a micrometer with a dial (address to an accompanying illustration). Alternatively, slowly rotate a disk and with the help probeов execute some measurements of a backlash between a disk and a motionless point, for example on a fixing arm of a support. If the received measurements are equal or exceed the maximum specified in Specifications, the disk is deformed and should be replaced. However at first check up a condition of bearings of a nave (the Head Maintenance service and the Head the Suspension bracket and a steering). Definitively to be convinced, remove a disk, develop on 180 and again establish on a nave if disk palpation still excessively, replace a disk.

5. Check up a disk on presence of cracks (especially round apertures under wheel bolts), other damages and deterioration signs. Replace a disk if it is necessary.


1. Turn away two bolts, fastening a support arm to a rotary fist, and pull together from a disk support assemblage together with колодками (address to an accompanying illustration). Tie up a support to a spring of a forward suspension bracket a wire and twine piece not to damage a brake hose or electroconducting of the gauge of deterioration колодок.

2. If the disk is not subject to replacement, put on it and a label nave. Turn away screws, fastening a disk to a nave, and remove a disk. If to make it it is not possible, slightly пристукните in a disk underside киянкой.


1. Make installation in the return to removal an order, paying attention to the following:
a) Clear and dry contact surfaces of a disk and a nave.
b) Level the labels made before removal, and tighten screws of fastening of a disk the effort resulted in Specifications.
If the new disk is established, use suitable solvent to remove from it a sheeting.
d) Before installation, clear a carving of fixing bolts of an arm of a support and cover their taking компаундом (Renault recommends Lostite Frenbloc). Place a support into position and tighten bolts of its arm the effort resulted in Specifications.
e) Establish a wheel, then lower the car on the earth and tighten wheel bolts the effort resulted in Specifications. Press a brake pedal some times to displace Pads closely to a disk.
