HELP..NO BRAKES!!!
« on: July 29, 2011, 10:49:33 PM »
Heres the deal.... I have built a wicked sandrail everything is awsome untill you want to stop then its a death trap!!!I only have rear brakes installed no fronts and a single lever steering brake. the issue is that no matter how well I bleed the brakes I have next to no braking action without pumping the pedal and the steering brake is next to usless. I have inspected the complete system and cannot find any leaks when I bleed it no air comes out. Is there trick to bleeding a system with steering brakes? Any help would be great .......Thanks

Discs or drums ?  If discs , calipers mounted with bleeders to the top?

If you pump the pedal numerous times and then you get a good pedal, then your pads are way out of adjustment. Pumping the pedal will push the wheel cylinder out a bit each time untill the shoe makes contact with the drum, then after you let go of the pedal the springs pull them back again and you have to pump it up again next time you use the brakes.
If you pump the pedal till you get pressure and hold it and the pedal gradually sinks then you have a problem with the master.
If you cant get any sort of pedal then its probably air in the system.
Hope this helps.

A friend said that I'd need a power bleeder with mine Jeff to get all the air out with the steering brakes. Haven't done it yet but that me be an idea

Welcome to the sandrail world!
I've got a single lever steering brake on mine. I bleed the brakes then re bleed again using steering brake. I'm not sure but I wonder if the piston in your after market pedal assembly has the right piston/plunger for drum brakes? (I've heard it can make a differance in how much pressure fluid is moved) either way I'd get away from the drums and put on disc makes a HUGE Diferrance in the performance of the steering brakes as well remember you've now only got to wheels braking. I used the CIP Ghia kit for along time now have 4 piston wellwoods.

You'll have to go down to Oregon on spring break when a bunch of us go!
