How to remove the power brake booster unit?

To remove the power brake booster unit, it is recommended not to disassemble it due to its complexity and critical relationship to brake performance. Instead, it is best to replace a defective booster unit with a new or rebuilt one. Start by unbolting the brake master cylinder from the booster and carefully move it forward to create clearance for booster removal, ensuring not to kink the brake lines. If there is not enough slack in the lines, they will need to be removed from the master cylinder. Disconnect the vacuum hose fitting from the power brake booster and locate the pushrod clevis pin under the dash that connects the booster to the brake pedal. Remove the retaining clip and spacer, if applicable, and slide the pushrod off its peg on the brake pedal. Remove the mounting nuts holding the brake booster to the firewall and slide the booster straight out from the firewall until the studs clear the holes, then remove it from the engine compartment. For installation, simply reverse the removal steps. If the fluid lines were detached from the master cylinder, it is important to bleed the hydraulic system.

Cadillac DTS Brake Booster

The Cadillac DTS Brake Booster is a such part that has the function of decreasing the applied force to actuate the brake, improving driving's feel of the brakes. The vacuum booster operates through the use of a sealed chamber that is situated in the brake booster; this amplifies the hydraulic pressure coming from the master cylinder and applies the force exerted by the driver every time he or she steps on the brakes' pedal. There are two main types of boosters used in Cadillac DTS vehicles: vacuum-operated boosters as well as hydraulic boosters. Vacuum boosters work on the of engine vacuum and atmospheric pressure whereas hydraulic boosters work on hydraulic pressure for brake application. While these are usually effective, they sometimes can run into problems and need such replacement equipment like the vacuum pump, check valve, and filter among others. Moreover, the performance brake boosters and even the power brake conversion kit are also offered in the markets for those consumers who are interested and want to enhance their braking system of the car.

Each OEM Cadillac DTS 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.
