• Q: How to replace the brake master cylinder on 2003 Chevrolet Trailblazer?

  A: A replacement process for brake master cylinder starts by using the parking brake followed by wheel blocking. Place rubber caps or plugs on the exposed brake pipe fitting ends after you disconnect the brake pipes from the master cylinder to stop fluid loss and contamination. First install the rubber plugs before you detach the master cylinder nuts and bolts to extract the master cylinder from the vehicle. Remove all brake fluid from the master cylinder reservoir before you take away the reservoir container when needed. The master cylinder and reservoir connection should occur first after which you must fill the brake fluid reservoir before proceeding with bench bleeding of the master cylinder. Replace the master cylinder inside the vehicle by tightening its bolts and nuts to 36 N.m (27 lb ft). Attach the brake pipes to the master cylinder while tightening each pipe nut to 30 N.m (22 lb ft). Close off the hydraulic brake system through a thorough bleeding process.
