Unbolt the master cylinder from its mounting points then take the entire assembly out of the car plus the connected reservoir. Begin by attaching the master cylinder reservoir before performing bench bleeding on the master cylinder for installation. Secure the master cylinder to the vehicle using hand torque until mounting nuts reach 36 nm (27 ft. Lbs.). Put the hose and clamp on the reservoir port for vehicles that have jl4 followed by removing the crimping tool from the hose. Secure the brake pipes to their exposed fitting ends and fasten them with 25 nm torque pressure to complete the connection. Reconnect the braking system sensor and install the upper fender support before performing brake fluid drainage to release the parking brake and free all wheels.
