The Stovebolt Site Forums The Shop Area General Truck Talk What type of front disc kit to use.

Anyone recently use product 71-975W6 disc kit from wwwclassic.com,on a 55 2nd series 1/2ton.and is any tweeking needed?and I can't tell in the pic,but does it include bearings?

I got one from POL. CCP has them and our sponser has them: American Classic Truck Parts. The discount we get does not apply to those kits. I just got it on sale at POL. They are all basically the same and have some caveats re: wheels and tweeking. Nothing major. Don't know which one you mean, there is no wwwclassic.com for our parts.

Used POL with good results. Good price too.

Strongly recommend against the CCP kit.

Care to explain?

I used this one. No problems.

Thanks for giving me the opportunity to publish my open letter to CPP here for the fourth time. Here is the text of the letter I sent then a couple years ago and until I receive the courtesy of a response from these people I will continue to recommend against buyng anything from them.


CCP,

My mechanic recently completed the installation of your Disk Brake Conversion #4759DBK-6 on my 1951 Chevrolet 1/2 ton pick up. I am writing with a couple suggestions to improve your instruction sheet, and to complain about the problems we encountered with some parts.

I would suggest that you make the following two revisions to your instructions:
1. Indicate the correct position of the offset of the Caliper Mounting Bracket. The instructions make no mention of this and if you guess wrong you have to remove the hub to correct the problem.
2. You should mention that the Steering Link spacers should be removed. There is no mention of this and again, if you do not do this you must remove the hub to correct the problem.

The following is a list of problems we experienced with the parts:
1. The aluminum spacer holes did not align with the hub from the front brakes causing misalignment and runout in the front wheels. A larger hole should be considered.
2. The brake actuator rod on the Power Brake Booster #4754BB is too long. I must be cut and rethreaded to fit.
3. The Master Cylinder bracket is not correct for this vehicle. It hits the cross member and must be modified to mount securely.
4. Both the master cylinder and proportioning valve leaked around the plugs that were already installed.
5. Both rotors were warped and had to be turned. You should suggest to turn the rotor assembly after it is assembled to allow for smooth braking.

I feel that the omissions in the Instructions, although frustrating, do not affect the quality of the conversion. However the defects in the master cylinder, proportioning valve and rotors, as well as the other problems encountered do not speak very highly of the quality of this kit or your quality control standards.

Furthermore these defects added almost $200 to the cost of installation by a 26 year Master ASE Certified Technician with 33 years race car and street rod building experience.

Once installed the braking is dramatically improved but the problems one can expect to encounter would not make your products something that I would recommend. 

Hopefully your customer service will redeem you and therefore your comments are anticipated.

Sincerely,
Woody Vondracek

I had some of the same problems installing it on a '54 GMC. I have no experience with the '55-59 kit other than the dual master bracket. Those problems detailed here.

Czechman and Cletis Thanks for the heads up. I was getting ready to order from CCP,Now probably not.Lowest bidder sometimes costs much more.

Czechman, thank you very much for taking the time to share your experience. One of the things I appreciate most is not having to learn something the hard way after somebody else has already had a bad experience doing what I'm thinking of doing.

Thanks again!

Thanks, for the info been looking to buy a kit. Have'nt been inpressed with Brothers either, going to get the disc brake kit from POL. Thanks Brett

I have installed both the CPP and POL kits on '54 GMCs. Be advised both will require some rework. Neither is a bolt on and go deal.
