Q: How to replace the brake master cylinder on Chevrolet Colorado?
A: First use the required tool to drain brake fluid from the master cylinder tank. Separate the electrical connector for the fluid sensor while using rubber caps to seal each end of the brake lines as you disconnect them from the abs module to the master cylinder. Take out the Brake Master Cylinder after unthreading its mounting bolts. Prepare the master cylinder through bench bleeding then install it onto the mounting studs. Bolt the mounting nuts into proper position and make sure they reach 30 n.m torque settings during tightening. Plug in the fluid sensor electrical connection followed by sealing the Brake Line tubing ends after installing them between the abs module and master cylinder unit. Tighten all fittings to 17 n.m (13 lb ft). Fill the reservoir with brake fluid while performing system checks and let air out through the brake lines.
Q: How to replace the brake master cylinder without RPO LAT on Chevrolet Malibu?
A: The Brake Master Cylinder replacement starts with depleting vacuum from the booster by removing its vacuum check valve. Disconnect the electrical connector from the brake fluid level indicator switch plus the master cylinder secondary brake pipe fitting. Seal the fitting with caps and close the outlet port to preserve the brake fluid. Apply this process to the connection of the main brake tube. Pull the master cylinder from its position when you unscrew all its mounting nuts first. Check for damage on the cylinder seal that connects the master cylinder to the vacuum Brake Booster. Replace if necessary. Take out the master cylinder reservoir when necessary. Place the Brake Master Cylinder reservoir onto the master cylinder if it was removed and carry out the bench bleeding process on the master cylinder. Place the master cylinder barrel seal correctly on the vacuum Brake Booster before attaching it. Secure the master cylinder nuts tightly to 25 n.m (18 lb ft). Fit the primary brake pipe connection first then the secondary one and fasten it using 20 n.m (15 lb ft) torque. Use denatured alcohol as a lubricant to place the vacuum check valve onto the grommet but stay away from using soap. Connect the brake fluid level indicator switch and let hydraulic brake fluid flow through the system.
Q: How to replace the Brake Master Cylinder with a Vacuum Brake Booster on Chevrolet Tahoe?
A: Before you start working install the parking brake then disconnect the Brake Fluid Level Sensor power wire. Before starting work disconnect the brake pipes to protect brake fluid from leaking out or being contaminated. Take off the master cylinder nuts and remove the part before getting rid of the master cylinder reservoir. Start setup by inserting the master cylinder reservoir. Afterward prepare the master cylinder for bleeding. Mount the master cylinder onto the vehicle while adhering to fastener notices found in service precautions and tighten the mounting nuts to 36 n.m (27 lb ft). Join the brake pipes end to end and tighten their fittings to 25 n.m (18 lb ft). Reattach the Brake Fluid Level Sensor electrical connection and perform brake bleeding before let go of the parking brake.
