2007 Chevrolet Colorado Brake Master Cylinder

The recommended torque is 17 N.m (13 lb-ft).

You need to remove the master cylinder from the vehicle, secure the master cylinder in a vise, next carefully remove the brake master cylinder reservoir retaining pins, and remove the reservoir from the master cylinder by pulling the reservoir straight up and away from the cylinder, then remove the seals from the master cylinder.

You need to remove the brake fluid from the master cylinder reservoir, remove the fluid lever sensor electrical connector, remove the brake lines from the anti-lock braking system (ABS) module to the master cylinder, then install the rubber cap and/or plug the brake lines, remove the mounting bolts from the master cylinder, and remove the master cylinder.

You should bench bleed the master cylinder, install the master cylinder on the mounting studs, install the mounting nuts, then install the fluid lever sensor electrical connector, and remove the rubber caps and or plugs from the brake lines, then install the brake lines from the ABS module to the master cylinder, fill the reservoir with fluid, then check the operation of the brake system and bleed the brakes if necessary.
