disk brake parts

Hello all,

Pulling my hair out over these brakes and feel I am making it harder than it needs to be.

Does anyone have part numbers (or year/make of donor) for a simple manual disk conversion? Just an 11" rotor, single piston set up as close to OEM as possible.

I do not need anything fancy. I prefer to buy the part separate if possible so i know what i am getting as it appears most kits are regurgitated offshore parts. (wilwood excluded). I have called called several manufacturers (I am going to start calling them "rebranders") and none are very specific.

I want to use my OEM spindles. they are already installed on new joints and do not want to beat them apart risking ruining them.

Many thanks in advance.
Chris

Re: disk brake parts

I bought a manual disc MC and hold-off valve from Ground Up. Purchased stock rotors and calipers from my local parts store. They are remanufactured GM calipers.

What year/model were the calipers and rotors from? what mounting bracket did you use?

disk brake parts

This is what I used to help me along. You will need to cut the spindle which was no big deal. You don’t have to be deadly accurate. You can bend the caliper bracket if necessary. I bought parts from Pirate Jacks (master cylinder, caliper bracket, dust cover), Amazon (Delco rotors, Raybestos loaded calipers) I got the brake hoses from Oreillys. If you look at the kits you can pretty much figure out any parts you will need. You existing hard brake lines should work.



Brakes



I just got parts for a 1969 Camaro. I used this proportioning valve and mounted it below the master cylinder. They also had the lines to go from the proportioning valve to the master cylinder.

I did it this way so it would look original and I could fit 14” steel wheels. PM me, I’ll help if I can.

It looks like this. Technically not “correct” proportioning valve but fits nicely and works well. It combines the two valves used on 1969 and makes it like a 1970 if I remember correctly.

I converted someone's 67 to 69 manual disc. You have to buy Chevelle/Monte Carlo calipers when installing them on a 67 Camaro. If you use 69 Camaro calipers, the a-arm bumper will hit the caliper banjo bolt. The Monte caliper brake hose is located differently to provide clearance. I grabbed the spindles and brackets from Ground Up since they are close to me. You can use a combination valve instead of the original distribution block and hold-off valve if you want. The proportioning valve is the one located on the subframe if so equipped. All the correct terminology is here: Camaro Brake Valves More info here: Brakes

Re: disk brake parts

I did the same thing long ago. 70 Monte Carlo calipers and brake hoses. 70 Monte master cylinder and combination valve. The car I put them on was a 69 with power drum brakes converted to disc/drum manual brakes.

What mounting bracket did you use?

69 Camaro and Monte calipers utilize the same bracket. The only difference is the hose location as I mentioned.

Re: disk brake parts

In the garage tonight and the bracket from the CPP kit or a right stuff CMB01 (same part) will fit my spindle.


I only see a bracket for a 4 piston caliper listed for the 67 and i get it,, that is what it came with.

Question, Is there a caliper bracket that will fit on my 67 spindle that will work with a single piston caliper?


My front end is together and I really do not want to beat the new ball joints apart to swap spindles.


thanks,

Re: disk brake parts

70-72 Monte Carlo should work. What are you using for spindles? Stock non-modified
drum spindles or stock disc spindles?

I have the stock drum spindles on the car. CPP said on the phone i could use them with their kit and that is incorrect. The top bolt boss area is outboard ~1" compaired to a disk spindle.

I can get my drum spindles off without damage but the CPP pushes my wheels out over 1/2 inch not zero like advertised, and the kit is full of no name parts.

Most likely purchase my part separately or order the Wilwood kit that adds .190 to the track and also saves on weight.

Re: disk brake parts

Chris, You can modify your drum spindles to work with 70-72 Monte/Chevelle calipers, etc.
You need to cut ~.61 off the upper boss and possibly tap the hole deeper. I've seen some
that did not need to be tapped and some that did. IIRC it's a 5/8-18 thread. It's best if the
surface is machined on a mill but if your patient and careful it can be done with a hacksaw
and sanded/filed smooth. The spindle can be removed without damaging anything if you know
how. It's really not difficult. Don't use a damn pickle fork.

I got the spindles free last might, Using the energy from the coil spring to brake it free.

that said,, is there a rotor that has less offset? I can use the .500 ones I have now but if it is as easy as ordering a different part I can ship these back.

Or did all single piston caliper brakes move the wheels out?
