Chevrolet Equinox Service Manual: Rear Disc Brake Mounting and Hardware Inspection Disc Brakes

Warning:Refer toBrake Dust Warning.

Inspect the fluid level in the brake master cylinder reservoir.If the brake fluid level is midway between the maximum–full point and the minimumallowable level then no brake fluid needs to be removed from the reservoir beforeproceeding.If the brake fluid level is higher than midway between the maximum–full point andthe minimum allowable level then remove brake fluid to the midway point before proceeding.

Danger:Do not use a service jack in locations other than thosespecified to lift this vehicle. Lifting the vehicle with a jack inthose other locations could cause the vehicle to slip off the jackand roll; this could cause injury or death.

Raise and support the vehicle. ReferLifting and Jacking the Vehicle.Remove the tire and wheel assembly. Refer toTire and Wheel Removal and Installation.Grasp the brake caliper housing and try to move the brake caliper housing up/downand forward/reverse in relation to the brake caliper mounting bracket. If excessivelooseness is observed the brake caliper bracket bushings and/or the brake calipermounting bolts may need to be replaced.Compress the rear caliper piston.Install a large C-clamp over the top of the caliper housing and against the back ofthe outboard pad.Slowly tighten the C-clamp until the piston is pushed completely into the caliperbores.Remove the C-clamp from the caliper.With the piston compressed into the caliper bore, grasp the brake caliper housingand slide it back and forth on the brake caliper mounting bolts. Check for smoothoperation. If the brake caliper housing slide force is high or the brake caliper housingdoes not slide smoothly, inspect the brake caliper mounting bolts and/or the brakecaliper mounting bracket bushings for wear or damage. If wear or damage conditionsare found, replacementof the brake caliper mounting bolts and/or the brake caliper mounting bracket bushingsis necessary.Remove the brake caliper mounting bolts from the brake caliper mounting bracket andsupport the brake caliper using heavy mechanics wire. Do not disconnect the hydraulicbrake hose from the caliper. Refer toRear Brake Caliper Replacement.Remove the disc brake pads from the brake caliper mounting bracket.Inspect the disc brake pad mounting hardware for the following:Missing mounting hardwareExcessive corrosionBent mounting tabsLooseness at the brake caliper mounting bracketLooseness at the disc brake padsExcessive contaminants in the brake caliper mounting bracket surface and threads.If any of the conditions listed are found, the disc brake pad mounting hardware requiresreplacement.Ensure the disc brake pads are held firmly in place on the brake caliper mountingbracket, yet slide easily on the mounting hardware without binding.

Inspect the caliper bolts-(1) for the following:BindingSeizingLooseness in the brake caliper mounting bracket-(3)Bent or damaged brake caliper mounting boltsCracked or torn boots-(4)Missing bootsBent or damaged brake caliper mounting bracket (3)If any of the conditions listed are found then the brake caliper mounting hardwarerequires replacement.Install the disc brake pads to the brake caliper mounting bracket.Install the disc brake caliper to the brake caliper mounting bracket.
