Question: Does this fit agaist the booster or is there a bracket between the master cylinder and booster on a 97 gmc sierra c1500?Bob C. / Sep 20, 2021
Hi Bob, I'm glad to assist you. The brake master cylinder is directly installed at the back of the brake booster on most vehicles. Click the link after this to see a general guide (DIY) how to install a brake master cylinder (https://youtu.be/StkzzZWr3Ac). This part is a guaranteed fit with the 1997 GMC C1500 all submodels, 6 and 8 Cyl 5.7L, 4.3L, and 5.0L. This is not compatible for the 6.5L engine. Grab our promo sale price offer and click the link below to order today. I hope this helps. Happy shopping.

Answered by Jeonino E. / Tue, Sep 21Question: What keeps the front brakes from locking up I already replace the front calipers in the rubber hoses and they continue locking up?Gilberto S. / May 26, 2021
Hi Gilberto, I'm glad to help you out. Since you already replaced the calipers and hoses, replacing the master cylinder could do the job. The brake master cylinder is one of the most important components found in modern car braking systems. It serves as the main valve that pushes brake fluid through the brake lines so that the brake calipers can squeeze the pads against the rotors. I hope this helps. To order the part, click on the link below while the part is in stock and take advantage of our ongoing sale today. Happy shopping.
