GMC Terrain Brake Booster
The Brake Booster is one of the important parts in GMC Terrain automobiles, as they help to decrease the required effort to apply the brakes. In the case of a booster, through the use of a vacuum chamber, it increases the hydraulic pressure from the master cylinder and enhances the efforts being made by the drivers to apply the brake. There are two basic categories of boosters, these are Vacuum operated and hydraulic boosters. In vacuum boosters, pressure difference between engine vacuum and atmospheric pressure is used and in hydraulic boosters pressure of the fluid is used for brake assistance. Traditionally, the vacuum power boosters are used in GMC Terrain vehicles, and although these are very reliable, they are prone to failure sometimes. Furthermore, one can also order performance brake boosters and power brake conversion packages for those who wish to give their vehicle's brakes a better setup.
Each OEM GMC Terrain Brake Booster 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 Terrain Brake Booster Parts Questions & Experts Answers
- Q: How to perform an operating check on the power brake booster?A: To perform an operating check of the power brake booster, start by depressing the brake pedal several times with the engine off to ensure there is no change in the pedal reserve distance. Next, depress the pedal and start the engine. If the pedal goes down slightly, the operation is normal. When it comes to removal, note that the power brake booster is not rebuildable, so any issues require its replacement with a new one. Begin by disconnecting the negative battery cable and the vacuum hose check valve from the power brake booster. Move the engine compartment fuse/relay box aside for clearance and remove the battery and battery tray. Once the engine is completely cool, disconnect the hose from the coolant expansion tank. Disconnect the sensor wiring harness from the master cylinder, remove the master cylinder mounting nuts, and position it aside without disconnecting the Brake Lines. Proceed to disconnect any electrical connectors from the booster and the electrical connector from the ABS hydraulic control unit, moving the transmission control module if needed. Put rags under the module to catch any spilled brake fluid and thoroughly clean the areas on the ABS hydraulic control unit where the hydraulic line fittings are connected. Disconnect the hydraulic lines from the ABS hydraulic control unit, making notes of their locations for reassembly, and seal all openings to prevent contamination. Depending on the model year, you'll either remove the ABS hydraulic unit mounting bracket nuts or carefully label and disconnect the brake lines from the ABS control unit and remove it along with the bracket. In the cab of the vehicle, remove the insulator panel located below the instrument panel on the driver's side (or remove the communications module and the Accelerator Pedal Position (APP) sensor on 2013 and later models). Remove the brake pedal position sensor and the clip and foam washer securing the brake booster pushrod to the brake pedal. After removing the four brake booster nuts, pull the brake booster forward and toward the middle of the engine compartment to remove it, also removing the foam seal if needed. For installation, reverse the removal steps. Lubricate the pushrod pin on the brake pedal arm with multi-purpose grease before connecting the pushrod to the brake pedal and installing the foam washer and clip. Install the ABS hydraulic control unit, tighten the mounting fasteners, bleed the brakes, and thoroughly test the brake operation before returning the vehicle to normal service.
