Chery A113 Maintenance Manual page 9

4.14 The area between the dustproof seal ring and the brake clamp
housing must be kept dry. It should be kept away from the brake
cylinder cream or the brake liquid, in order to ensure the correct
position of dustproof seal ring.
4.15 Secure the brake piston with the reinforcement parts available
in market and press it onto the dustproof seal ring slightly. Blow the
dustproof seal ring with compressed air (up to 3.0bar) to attach the
piston ring onto the piston.
Notice: Dip the dustproof seal ring and piston with brake
liquid to facilitate the passing of the seal ring.
4.16 (Checking of brake disc) Check the thickness of brake disc.
Replace the brake disc if the thickness is less than the min thickness.
Notice: The two brake discs at the same axle should be replaced at a
time. The friction linings must be replaced following the
replacement of the brake discs.
4.17 Check the max run-out of the end surface of brake disc with
dial gage. If above 0.03mm, replace it. (Provided that the brake disc
thickness is guaranteed, it may conduct the proper machining to
meet with the max run-out.)
4.18 Installation of other portions with reference to the Removal
Procedure.
