So I got a power break booster when I bought my truck and I took off the tiny leaky old master cylender today and was looking at the power break booster he gave me but the bracket on the back will not clear my stearing could someone help me on this one or show me some pictures of their power break setup mostly how it mounts up?

Here is a picture of the booster with brackets. It mounts to the firewall like it is sitting. If no one else posts the a pic of a booster mounted to the firewall I will take one and post it.

That is a nice looking booster! What color were they from the factory? I bought one off E-bay and but it is brownish orange (rusty )! Thanks in advance this board rocks!

Where did you get that and how much did that set you back?

I'm trying to see how those brackets would be anywhere near the steering.

Could it be that the rear bracket is installed upside down
here is a thin one and another picture of one.

I just installed an 72 unit in my 68 and works great. There are pics of mine during the install.

what brake booster is that one that JimKshortstep4x4 has posted? i have the other thin style, and i think the one jim posted is suppose to be a better booster.. dual diaphram unit right?

Sonny · 03-06-2005, 11:02 PM

I think the thin one is dual diaphram too. One is a bendix and the other is a delco from the way I understand it. Anyway I have the thin and if jump on the brakes, it feels like my truck is going to flip over! Amazingly the brakes feel pretty balanced too (front to rear).

The pictured one is off a 3/4 ton 70 and older....4 wheel drum. The one you describe is typical of a disc/drum 1.2 ton

Striker169 · 03-07-2005, 02:39 PM

See my bracket looks exactly the same but there are 6 bolts on the back instead of 4 so I think im just gonna cut off the bottom 2 and just bolt up the 4 that are susposed to be on and it will fit.

Is that really all you need to do to add power brakes, simply toss a booster in front of the master cylinder?

Can you buy one from an auto parts store, or would it be better to visit the bone yard for one?

Sonny · 03-07-2005, 05:37 PM

Make sure you grab the rod that connects to the brake pedal too. All I did was grab the whole assy and use the old booster and master cylinder for a core. You can get the master cylinder and booster as a assembly and save you some work. you will have to mfg new brake lines because the master cylinder is so far foward. You can see the ends of my brake lines where they hooked up to the old master cylinder:

My truck is a 68 C10 and I got the power brake setup from a junked 72 for $25. Oh , yeah most importantly grab the fittings on the brake lines going into the proportioning valve to save you a headache trying to match up the fittings. Other than that it was a straightforward swap.
