My situation is this, I have 4 wheel disk brakes on my 51 1/2 ton Chevy 3100. I purchased the disc/disc power brake master cylinder set up. Thought this would be pretty straight forward, i am mounting it under the cab in the normal position.1st question is there a specific size of brake line ?? I went to parts store and found out there are about 3 sizes?? Is there a certain size or does it matter?? i bought 3/16th's! Also proportioning valves? From what I have read I need this because of where the system is mounted? help please. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | The 3/16 lines should be sufficient. If you bought a kit the proportioning valve should be on the master cylinder. It looks like this on the Performance on Line kit. Read about my installation on my '54 here. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | area51...I too used the underfloor set up but I did not put a proportioning valve and I do not have disc brakes....however, on my 52 there was one line, 1/4" if I remember right, that crossed over to the chassis rail and then it was all 3/16.
...don't know if this applies to your situation or not but just food for thought. | | | | | Joined: May 2011 Posts: 266 Shop Shark | | Shop Shark Joined: May 2011 Posts: 266 | Thanks guys,
Cletis that is exactly what mine looks like. Yes the exiting line is 1/4 inch but it will be reduced to the 3/16's. I googled and read a few things last night.i found out about all the different fittings, pipe,ansi, etc... I think i got it figured out but will certainly read your instal. | | | | | Joined: May 2011 Posts: 266 Shop Shark | | Shop Shark Joined: May 2011 Posts: 266 | Cletis read the write up good info, I have my master cylinder and pedal already installed. My disc brakes were not a conversion i have a ford 8.8 rear end.My headache was slightly less than yours. I did have to "make" the assembly fit. I cut some of the stock assembly bracket away to do this worked out fine, about 7 hrs. worth of fitting and grinding??
Again thanks for the info. | | |
