Adjusting brake booster questions.

Well I installed a brake booster to convert from manual to power drum brakes. It wasn't a full kit, just the booster with 2 rods and a clevis and a couple of hardware pieces. OH - and NO instructions, thanks Right Stuff. Here is the booster I bought. https://www.summitracing.com/parts/RSD-RPB1001


It worked great at first, but now the brakes are dragging - hard. I am using it with the manual brake master cylinder, it has a 1" piston.

I assume I just need to shorten the rod from the brake pedal to the booster?? Yes, I used the lower hole. I did adjust the rod longer than the manual brake rod.

I read that I'm NOT supposed to use the pedal return spring, is that true? The return spring currently is not hooked up.

Last - the brake pedal DOES hit the stop at the top of the return. I also read it should not??? Where should it stop, and the spring should NOT be used? Why??

Thanks for the help.

Re: Adjusting brake booster questions.

Yep, I'm going to try that here in a few minutes. I might also remove the bump stop since it's not needed.

I read in an old post that another test is to unbolt the master cylinder and see if it frees up.

I think I just have the clevis just adjusted too long.

Thanks for the input.

Also - I'm going to pull the master cylinder anyway to make sure I didn't put the push rod in backwards.

I had to cut the rod length on mine. I don't remember how much but I did shorten it.
