spongy brakes I need help bleeding I think

Postby trei75bronco » Thu Mar 13, 2014 8:46 am

I have been trying to bleed the brakes solo and I think I'm sucking air into the system. I have brakes but I have to pump up pressure. I think I need a pedal pumper and be able to watch the flow. Here is my setup cuz everyone asks

JBG booster kit
Disc disc proportion valve
Gm rear calipers
3/4 ton front brakes
New lines from Mc down to axles
Have no leaks as far as I can see.
Bleed valves are up as much as possible
Booster has vac
Adjusted pin on booster into Mc

I bought a mity vac but it seems to be a little hard to keep it sealed

Any advice

I assume your doing one wheel at a time. I always start with the furthest back from the mc - passenger rear then work my way forward.

You really need someone to pump the brakes while you open and class the bleed screw.

I open. Pump 3-4 times then pedal all the way down close screw. Let up on pedal. Then pedal down and open screw. Then close screw. Pedal release. Pedal down. Open screw. Repeat 6 or 7 times until no air bubbles seen.

Sometimes it helps to not open the bleeder fully as some air sneaks in at the screw. Also I always run a clear tube off the bleeder screw into a bottle to help the mess and watch.

This works for me but your mileage will vary ;)

Ive had lousy luck with vacuum bleeders. Youre on the right track getting help.

It's just almost impossible to do it solo. I prefer old school bleeding procedure and closing the bleeder on a down stroke
