Remove the cap from the brake fluid reservoir, then loosen the wheel lug nuts and raise the front or rear of the vehicle, supporting it securely on jackstands while blocking the wheels at the opposite end. If the vehicle has electronically modulated air suspension, ensure the height control switch is turned off before raising it. Remove the wheels and work on one brake assembly at a time, using the assembled brake for reference if needed. Inspect the
Brake Disc carefully; if machining is necessary, remove the disc to also take out the pads. Push the piston back into its bore to create space for the new brake pads, using a C-clamp to do so, and ensure the fluid in the master cylinder does not overflow, siphoning off excess if needed. For front brake pad replacement, wash the brakes with brake cleaner before disassembly and follow the provided illustrations in order. For rear brake pad replacement, wash the brake assembly first, then depress the piston with a C-clamp after cleaning. When reinstalling the caliper, tighten the mounting bolts to the specified torque, and after completing the job, firmly depress the
Brake Pedal several times to bring the pads into contact with the disc. Finally, check the brake fluid level and add if necessary, ensuring the brakes operate correctly before returning the vehicle to normal service.
