54-71098 Power Brake Booster, for Chevy Blazer for GMC C1500 C2500 Suburban

Cheap replacement that works perfectly

As a retired aerospace engineer, I measured everything in comparison to my old ‘99 4Runner brake booster and found that this new one, purchased here, was perfect, down to the thousands of an inch, was easy to install, in less than hour, (with Jesus prayed into it) and now I have the best brakes ever!

Everything hooked up just fine worked fine. The shipping was quick thank you very much.

Update: So ive had it installed for only a month and its started to fail. Adjusted the foot pedal and still failing. Less then 1,000 miles. So far it's working great easier to put in then I've seen in videos. Great price saved over $300 that the parts stores charge.

Put it on my 1997 4Runner SR5 4x4 that would lose power brakes intermittently. With 330k miles, it wasn’t worth deciding between the check valve or the booster diaphragm. And for $70, not worth the time to investigate. New one was a drop in, took about 30 min. perfect fit. 1) remove the spring and cotter pin from the pedal linkage pin 2) remove the pedal linkage pin 3) unbolt the 4 nuts to the firewall. I used a deep well socket and u-joint/swivel extension. worked well. 4) pull the vacuum line under the hood 5) unbolt the master cylinder 6) Install in reverse. NOTE: my factory nuts were 12mm but the new ones were 13mm. was all I needed except a 10mm to drop the dash panel because i accidentally let the other end of the pedal spring unhook from the dash. So keep an eye on that. There’s a plastic protective boot on the pedal side you need to remove first. My OEM booster had a grommet that goes the between the booster housing and the firewall. New one didn’t have this so i installed the original. It was in good shape. did not have to remove the master cylinder, just removed the 2 nuts and pulled it forward to slide the booster out.

I hesitated to install this aftermarket brake booster but decided to give it a try. My brakes suddenly got very hard to stop. Checked vacuum with gauge and no problem with booster vacuum valve, so assumed booster was bad. I also decided to replace the master cylinder (also aftermarket) as well because it would slowly go to the floor at stop lights. I spent about $200.00 for parts. Working great after 2 two months. Hope it lasts. Good deal if it does.

this part started to leak after 2 weeks and now they dont have any more to replace it and dont know if they will be able to get more UPDATE. I worked with the manager over the issues with the brake booster, and they were very helpful and took care of the problem. Their service is great better than any company I have dealt with, answered my messages in a timely fashion, and was courtesy and helpful. I will buy from this company again as I need parts, I have changed my star rating for this company and their services

Fast shipping and way cheaper than OEM. Installation was straight forward and had it installed in couple hours. So far so good. I'll give it a 5th star if it holds up for the foreseeable future. I knock off a star because it has developed an audible clicking noise when I depress the brake pedal more than half way. My 4Runner still stops like it should but that loud click it pretty annoying.
