Brakes are next on the 49 burb. Need advice on brakes. I want power brakes. Do I use a suspended pedal with a firewall mounted master cylinder/vacuum booster or a frame mounted unit with the original pedal and linkage? Would like to know advantages and dis advantages of both systems from anyone who has been through this. Also am I correct to assume that the AD pickup and burb frame are the same? | | | | | | Anonymous Unregistered | | Anonymous Unregistered | weeds, do a search on the forum for brakes or do a search for cletis, he just installed a system on his truch that he's rebuilding.

Now will do a search for cletis | | | | | Joined: Sep 2004 Posts: 2 Junior Member | | Junior Member Joined: Sep 2004 Posts: 2 | Weeds, I just installed a frame mounted power brake system from RBs Obsolete on my 51 Burb.
The pluses are that it is out of the way and is keeping my firewall clean. It also maintains the stock look of the suburban without clutering up the engine compartment.
The minuses are that it is OUT of the way and checking the fluid level is a joy because the original master cylinder was single bowl with a hole cut in the floor and I upgraded to the dual.
If you take the frame route for your installation, make sure to install the proper residual pressure valves and a proportioning valve (Summit has a fairly good price on them).
If the body is off the frame, the chassis mount is a great deal easier as well.
Aside from the fluid check situation, I personally like the semi-stock look of keeping the booster and master cylinder hidden.
Hope this helps and best of luck!

Thanks for the good advice on brakes. I need an education on proportioning and residual pressure valves. What are they and what do they do? My donor IFS and rear axle are out of an 84 GMC half ton. The front end came with the power steering box and the dual master cylinder. The booster was missing. There is what appears to be a proportioning valve there also. Can I use any of this stuff over? Cletis thanks for the pics. I have all the popular catalogs except CCP. Pop E-mail about CCP. Thanks to all . | | | | | Joined: Sep 2004 Posts: 2 Junior Member | | Junior Member Joined: Sep 2004 Posts: 2 | Weeds: The residual valves keeps constant fluid pressure to your brakes instead of the fluid being returned to the master cylinder. Discs use 2 lb. valves and drums use 10 lb. valves (each in the line between the master cylinder and the brake). This is if you decide to do the chassis mount master cylinder where your M.C. is level with or below your brake lines.
On the topic of proportioning valves, I reused an old proportioning valve on a Mustang set up I did and it almost cost me the car because the fluid wouldn't hold on hills (thank god for e-brakes!) I swapped it out for the one summit has (p. 212 in the new mag if you get it). It runs about 40 bucks and was worth it. Essentially is allows you to keep full pressure on your front brakes and allows you to control the pressure to your rear brakes.
Even if you decide not to do the chassis mount M.C., you should still replace the proportioning valve in my opinion. It will save you some headaches in the future!
Hope this helps! Best of luck!

I will take your advice and use new stuff throughout. I would like to post some pictures of my project but I can't seem to figure out how to do it. Im going to have to get my grandson to show me how. Thanks again. Weeds | | |
