Start by disconnecting the car's negative
Battery Cable from the post before addressing the twin
Piston disc brake caliper. Attach your brake pedal holding tool on the brake pedal to push it past the first inch, Alfred Harry. Elevate and support the vehicle before removing the nuts from the wheel's mount and the entire tire and wheel unit. Before installing the flexible
Brake Line, remove the banjo bolt, discard the old washers and put new ones on during reinstallation for AWD. The process for RWD is to use the appropriate sealing washers and banjo bolt. Once you have the guide pins, unscrew the bolt holding the caliper to the caliper guide and move the brake caliper from the
Brake Pads and adapter. Clean and check the caliper before you start disassembly, since air pressure on the piston can lead to serious injury for the user. Take out the brake fluid from the caliper, use a vise with protecting jaws, apply a short blast of low-pressure air with a C-clamp and some small blocks of wood to move the pistons out. Take off the dust boots and seals from the piston slowly, so you do not hurt the aluminum part and clean each piston bore and passage with a cleaning agent. Check the caliper for damage, leaks and cracks and if it does not look good, either recondition it or replace it. When doing the installation, keep the area clear of debris, use fresh brake fluid to gently lubricate the pistons and seals and fitting new seals and dust boots is recommended. Position the dust boots rightly and fit the caliper bleeder screw, tightening it to 15 Nm. During installation, gently pull out the caliper pistons, securely cover them as you work and join and secure the caliper to the adapter with the guide pin bolts tightened to 60 Nm. Put on new washers on the banjo bolt and tighten it to 50 Nm, then close the tire and wheel assembly, tightening its nuts to 150 Nm. Now you're ready to finish: lower the vehicle, release the holding tool from the brake pedal, attach the negative battery cable, release all air from your braking system, conduct a test drive and see if everything works properly.
