I have been a member here for quite a while but all I have been doing is quietly reading messages and not saying anything. Now I would like to ask a little help from the Big Bolt gang about my brakes. I have a '52 chev. 6403 that I have shoehorned a 350 with an Eaton 5 speed in and now that it is moving I have turned my attention to stopping. I have rebuilt all 6 wheel cylinders and the master cylinder. I blew all the old fluid out of the lines and purged with fresh fluid. I replaced all the bleeders with new ones and adjusted the brakes. I have been trying to get these bled for the last 3 days and I cannot get a firm pedal. If I pump them about 10 times it starts to firm up but that is about as good as I can get. When I pump the brakes I can hear the vacuum canister cycling so I am guessing the diaphram is good. I don't know where to go from this point. Any input would be GREATLY appreciated. Thanks :confused: | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | Did you bleed the Hydrovac Booster first. | | | | | Joined: Jul 2002 Posts: 188 Member | | Member Joined: Jul 2002 Posts: 188 | I haven't worked on a system with a hydrovac, so I can't help you there. When I put my 3600 on the road I had the same problem. The cure was to really adjust the brakes until I could not turn the wheel, then back off the number of clicks listed in the manual. If you have Huck brakes, you will have to do this for each shoe. I followed the instructions in the manual to a tee and viola! had great pedal. | | | | | Joined: Jun 2003 Posts: 5 Member | | Member Joined: Jun 2003 Posts: 5 | I did not bleed the booster first but I did bleed it. I have adjusted the shoes very close but, I don't have a shop manual with exact procedure protocol. Does anyone know if there is a procedure online anywhere? | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | Hey Dave, Purchase a Chevrolet Truck Shop Manual,for your year truck. Everything you need to know is in there. I've been a Truck, & Bus mechanic for 23 yrs. now, but I still make it a point to have a Service Manual for everything I own. | | | | | Joined: Jun 2003 Posts: 5 Member | | Member Joined: Jun 2003 Posts: 5 | Hey, thanks alot guys. I appreciate the input. I have to leave town for a few days so, will get on it when I get back. | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | If your brakes pump up, it's usually an adjustment problem. Adjust your brakes, work your brakes, adjust some more, etc.,etc. It's a process but it's a must-do for safety's sake.
