Brake pedal return spring? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Free Candy Inside · 04-16-2018, 10:37 AM

I recently did a 73-87 front K swap into a 65 c10. I made a mount for the power brake booster (purchased new). I had a piece machined for an adaptor to use a stock booster that then allows the stock brake pedal adjuster to thread on. The brakes work great but the pedal will not return after pressing them, leaving the brakes dragging. I’m using all the stock 65 pedal assembly.

For anyone who has done a similar swap did you have to add a return spring to the pedal? Seems simple enough but wanted to see what majority did and make sure I’m not missing anything/have another issue.
Thanks in advance!

Did you check to make sure nothing is on a bind?

Everything works well except the pedal does not return. Use your foot to bring it back and everything is good.

When this happened to me it was because I over-tightened the booster rod at the pedal. I loosened it up a little and the pedal returned with no issues.

Is the stock return spring not in place?

Here is the brake pedal bracket all assembled including the brake booster, your's should look similar including the spring.

Rockenrod,

Love the photo of the booster assembly. Clarifies a few things for me. Did you drill the brake pedal clevis one inch lower on the pedal or is the brake rod still in the original position/hole?

Yes it's drilled lower.

I may have done the same. I’ll check that when I get home. Be an easy fix if that’s all it was!

For the win! I loosed the bolt slightly and now it works properly. Easy enough fix. Thanks for the help. Guess I just assumed it needed to be tight being a brake part. Lol
