Brake Question
Got a brake question, I have bled the brakes starting with closest, depress pedal and open bleed valve and fluid shoots out with plenty of force.
Pedal never tightens up, brakes only work when almost to the floor. No leaks, I'm thinking master is bad? Is there something with the master I can check or am I SOL? Thanks, ![]()

Re: Brake Question
I was always told to start bleeding with the farthest...
Maybe that would help. OR, is it drum brake? are the drums adjusted correctly?

Re: Brake Question
My buddy got all new CPP discs on his 71. We had to bleed the crap out of it to get a pedal....

Re: Brake Question
Start bleeding at the furthest which is the left rear, then right rear, right front, and then left front and see where your brakes are at. Also check to see that you are getting fluid at all 4 calipers. If not it is possible that the valve in the proportioning valve has slid one way or the other and needs to be centered again. POL sells a little tool that keeps the valve centered until you get the brakes bled.

Re: Brake Question
bleeding either way works, (close first, close last). doesn't take as long if you work your way from the master cyl back.
you have a modified brake system. lots of possibilities with the installation. |

Re: Brake Question
Bled from back to front, used clear tube and plastic catch. No air bubbles at all seen in the clear tube. Pedal gets a tiny bit better, let it sit for a minute and back to having a live pedal only on the last 10% of travel.
It's enough to stop the truck but I'm not liking it and I'm tired of brake fluid ![]() Any ideas or help is welcome.

Re: Brake Question
Did you drill a new hole on the brake pedal. When I put power on mine I had to drill a hole about 1 inch below the factory hole. That took up all the slack.

Re: Brake Question
Did the brakes ever work, or is this a brand new setup?
If new, did you bench-bleed the master cylinder (or firewall-bleed it with brake lines disconnected? Are the bleed screws located on the top of each caliper?

Re: Brake Question
Brand New Setup, CPP disc and master, I firewall-bleed it with lines disconnected. I'm not seeing any air in the lines.

Re: Brake Question
You need to drill the new hole and move the rod. Makes a big difference. And by a crap ton, I mean 7-8 full bleeds...

Re: Brake Question
Adjusted the length of the push rod and I think we are getting somewhere. I will start over tomorrow and move the hole down.
Thanks for all the help ![]()
