How to service and repair a front Brake Calipers (single piston) on GMC Jimmy?

First drain all brake fluid from the front brake caliper (single Piston). Then pad its inside with clean shop towels. Handle the Piston carefully because putting your fingers close to it when blowing air exposes you to severe wounds. The system must not have strong air pressure pushing out the Piston to protect it from harm. Pull the Piston and its seals out from the caliper housing bore without harming the metal surface and avoid putting tools made of metal. Wipe down the bleeder valve along with all caliper components in denatured alcohol before drying them thoroughly and blowing out brake fluid passages through clean filtered air. You must replace the Piston or caliper parts that show signs of surface wear, rust, chrome wear, or pit erosion. Before installing the Piston seal use cleaning brake fluid to lubricate the caliper bore, new Piston seal, and Piston. Place the Piston seal installer (J 26267) item on the new seal and ensure it remains free from twisting. Position the boot onto the Piston first then put the Piston into the caliper bore and lastly push the boot inside the chamber through the installer. Install the bleeder valve piece into the caliper body before final tightening to 12nm.

How to Replace Front (Single Piston) Brake Calipers on GMC Jimmy?

A brake caliper replacement on the front (single Piston) starts with draining two-thirds of fluid from the master cylinder reservoir. To start the replacement process securely lift the vehicle and install equipment safety stands after that remove the tire and wheel assembly. Place a c-clamp across the outer Brake Pad and caliper, while tightening it until the Piston reaches the bottom of the caliper bore then you can remove the clamp. Remove the front brake hose fitting along with both gaskets from the caliper while dispensing the brake hose fittings and discarding the gaskets and plugging holes. After removing both caliper mounting bolts and caliper from the assembly, proceed with brake lining removal and discard the rubber o-rings. Check mounting bolts and sleeves for corrosion and immediately replace found corroded pieces while inspecting the brake hose fitting bolt for blockages which require removal of blockages when detected. Check linings for wear and inspect the caliper for damage. To begin the installation process first apply delco silicone lube (GM P/N 18010909) or equivalent on both sleeves and bushings then mount the new set of rubber o-ring bushings to the caliper and the caliper mounting bolt sleeves. Squeeze the inner edge caliper boot next to the Piston until it pushes trapped air out before flattening the boot below the Piston face. Place brake linings inside the caliper before you install the two mounting bolts alongside the caliper and tighten them to 51 nm (38 ft. Lbs.). First squeeze the lining ears next to the caliper before you install the brake hose fitting and both new gaskets together with the brake hose fitting bolt. Tighten the brake hose fitting to 54 nm (40 ft. Lbs.). Use a file to modify the corners of the front brake caliper mounting holes on the Steering Knuckle until the specified range of clearance is reached. Check for damage when the total clearance measurement exceeds this limit. Check that the total measurement of the clearance gap between caliper and Steering Knuckle falls between 0.26 - 0.60 mm (0.010 - 0.024 inch). The procedure ends with a bleed of the caliper followed by wheel and tire installation and a low vehicle position then a leak check for the brake system.

The Brake Calipers of GMC Jimmy vehicles applies force on the brake pad to press it on to the rotor with the aim of producing equal and opposite force that will halt the car. These calipers come in two main types: The two common types of capital leases are: and include; Fixed and Floating. Fixed calipers use two opposite pistons to hold the disc, exercise better performance but they are not very accommodating to disc surface imperfections. Whereas floating calipers operate on the floating plane relative to the rotation axis of the disc, and employs a single piston to force the inner brake pad and slide and apply pressure on the both ends of disc. Nonetheless, floating calipers tend to seize for some reason, which in turn affects car fuel economy and leads to such consequences as disc overheating, and the pads' uneven wear. Different designs of brake calipers are also employed in the rim brakes of bicycles.
