GMC Sonoma Wheel Cylinder
The Wheel Cylinder in GMC Sonoma is a vital unit of the brake system that press the brake shoes to the brake drum in order to create the friction and bring the car into halt as desired. To accomplish this goal, this hydraulic system incorporates one or more pistons, cup seals, and an expander spring all enclosed in a cast iron or aluminum housing. When the brake pressure is applied, the pistons pull outwards exerting pressure on the shoes that Claudes against the drum, while the spring exerts pressure on the seals to ensure that there is no leakage of the fluid. Eventually, moisture accumulation in the brake fluid damages the cylinder surface and thereby causes fluid leakage and diminishing of brake force. Inspection and possible replacement or even reconstruction of the wheel cylinder are required to maintain the proper condition of brake parts, and the safety of a vehicle on the road.
Each OEM GMC Sonoma Wheel Cylinder we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
GMC Sonoma Wheel Cylinder Parts Questions & Experts Answers
- Q: How to remove the brake drum,brake shoes and Wheel Cylinder on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?A: To remove the brake drum and Brake Shoes, start by unscrewing the brake line fitting from the rear of the wheel cylinder using a flare-nut wrench to avoid rounding off the corners. Be careful not to pull the metal line out of the wheel cylinder. Next, remove the two bolts securing the wheel cylinder to the brake backing plate and then remove the wheel cylinder. To prevent the loss of brake fluid and the entry of dirt, plug the end of the brake line. For the overhaul process, disassemble the wheel cylinder by removing the rubber boot from each end, pushing out the pistons and cups, and removing the cup return spring and expander. Replace the rubber parts with new ones from the rebuild kit. Inspect the pistons for scoring and scuff marks and replace them if necessary. Check the cylinder bore for score marks and corrosion, and if present, consider honing or replacing the cylinder. Clean the cylinder with brake system cleaner or denatured alcohol and ensure the bleeder screw hole is clean. Lubricate the cylinder bore with clean brake fluid and insert the new rubber cups, making sure the lip faces in. Install the expander spring and remaining cup, attach the rubber boots to the pistons, and then install the pistons and boots. Finally, for installation, attach the brake line to the wheel cylinder before tightening the mounting bolts and line fitting. Use a flare-nut wrench if available. Bleed the brakes and thoroughly test their operation before driving the vehicle in traffic.
