GM 89026844 Pad Kit,Front Disc Brake

To remove and install disc brake pads, avoid inhaling dust from brake surfaces and use a commercially available brake cleaning fluid. Replace disc brake pads in axle sets only. Begin by using a syringe to remove two-thirds of the brake fluid from the master cylinder reservoir, then raise and safely support the vehicle. Remove the wheel and tire assembly, reinstalling two lug nuts to retain the disc brake rotor. Detach the disc brake caliper from the mounting bracket without disconnecting the brake hose, and suspend the caliper with wire from the coil spring. Use a small prybar to disengage the buttons on the outboard disc brake pad from the caliper housing and remove it, followed by the inboard disc brake pad. Inspect the disc brake rotor and machine or replace as necessary. For installation, clean the caliper piston boot with denatured alcohol, then use a C-clamp to bottom the caliper piston into the bore, ensuring not to damage it. After bottoming the piston, use a small tool to lift the inner edge of the boot and press out any trapped air. Install the inboard disc brake pad by snapping the retainer spring into the piston, ensuring it lays flat and does not touch the boot. Next, install the outboard disc brake pad, positioning the wear sensor correctly based on the vehicle model. Reinstall the disc brake caliper, followed by the wheel and tire assembly, and lower the vehicle. Apply the brake pedal several times to position the caliper piston and seat the brake pads, then check the brake fluid level and add as necessary. For inspection, check the disc brake pads every 6000 miles or whenever the wheels are removed, focusing on both ends of the outer pad and the inner pad through the caliper. Replace pads when any lining thickness is worn to within 1/22 in. (0.76mm) of the backing plate or rivet, and note that the outer pad has a wear sensor that produces a warning noise when replacement is necessary.

To be replacing and removing the brake pads, commence by uncapping the brake fluid reservoir and using a suction gun to siphon off two-thirds of the fluid. Next, loosen wheel lug nuts, lift the vehicle up, and support it by jackstands that are secure. Remove the wheels at front or rear ends; check the condition of the disc. If machining is required, remove disc, calipers and pads. For the removal of frontal pad wash brake assembly with brake system cleaner and push piston back into bore with C-clamp. Take out bottom caliper mounting bolt, rotate caliper upwards till inner & outer brake pads are removable .Take out anti-rattle clips and check them for wear. Lubricate caliper mounting bolts when reinstalling upper & lower anti-rattle clips as well as outside/inside ones.Apply 5 force on tightness of mounting bolt.Presently you can place wheel into position; lower your car down until tire touches ground; tighten lug nuts.Finally apply then release brake pedal before checking fluid level prior to test drive of brakes.Rear pad removal can only be accomplished after washing brake assembly as well as releasing parking break cable in addition to removal of lower caliper mounting bolt.Turn up caliper to detach from retainers plus take out pads.Installing requires putting anti-squeal compound on backing plates in addition to rotating it so that piston goes inside while new pad rattle clip should be attached.Lubricate caliper guide pin when turning down caliper installing mounting bolt.Reconnecting involves installing parking break cable henceforth put wheel while lowering auto; tightening lug nuts.Release brake pedal but do not hold it instead repeat until all air is removed from hydraulic circuit.Check if there is enough fluid otherwise top up reservoir before testing braking system.

Tighten the sleeve bolt and cable support bracket, reinstall the wheel and tire assembly, lower the vehicle, apply the brake pedal to seat the pads, and check the brake fluid level, adding as necessary.

To install, lubricate the caliper mounting bolts, install the upper and lower anti-rattle clips, and install the outer and inner pads. Position the caliper and tighten the mounting bolt. Install the wheel, lower the vehicle, and tighten the lug nuts. Finally, apply and release the brake pedal, check the fluid level, and test the brakes before driving.

Install the brake pads on the opposite wheel, then install the wheels and lower the vehicle. Add brake fluid to the reservoir until it's full. Pump the brakes several times to seat the pads against the disc, then check the fluid level again. Check the operation of the brakes before driving the vehicle in traffic. Try to avoid heavy brake applications until the brakes have been applied lightly several times to seat the pads.

Work on one brake assembly at a time, positioning a drain pan underneath and cleaning the caliper and surrounding area with brake system cleaner. Use a C-clamp to push the piston back into its bore, being careful not to overflow the fluid in the master cylinder.

Work on one brake assembly at a time. Push the piston back into the caliper bore to provide room for the new brake pads. A C-clamp can be used to accomplish this. Remove the C-clamp. Remove the two caliper mounting bolts. Lift the caliper off the disc and remove the outer pad. Pull the inner pad out of the caliper and remove it. Fasten the caliper out of the way with a piece of wire to prevent damage to the brake hose. Remove the mounting bolt seals, then use a scribe or similar tool to extract the rubber bushings from inside the caliper ears. Clean the caliper and mounting bolts and check them for corrosion and damage. Replace the bolts with new ones if they're significantly corroded or damaged.

On older models, remove the caliper mounting bolts and lift the caliper off the disc, removing the outer and inner pads.
