Default Disc Conversion Kit

Hello everyone,
Today I discovered two leaky front wheel cylinders and after many years of wanting to do a brake conversion this episode is pushing be closer!

I have a 1959 convertible with A/C and a Kelsey Hayes under the dash mounted booster. I also have 14 inch Kelsey Hayes spoke wheels the original stabilizer bar. (I would not mind changing the stabilizer bar during this conversion to stop some of the body roll. In the distant future I would also like larger wheels and tires without tubes)

I am looking for help deciding on a complete disc conversion kit to install either a two or four wheel disc brakes.

Does the A/C unit/valve covers interfere with the boosters? When I call some “kit companies,” some of them are not sure and some of simply say “no”….some offer brake light switch, e-brake cables (4 disc). Basically, a purchaser (like me) can’t get straight answers or compare apples to apples.

So far this company seems to be the most informed and the sell the most complete kit. The operator did say that the booster in the picture is not the one for a 59.

Any help/feedback would be greatly appreciated.

Here's a great thread that details Ray Clark's disc brake conversion. He has A/C and will let you know exactly what you need to do the conversion. The TRL also has information on doing the conversion. And yes, A/C does interfere with doing a normal conversion.

Default Disc Conversion Kit

Hi Sherman, First of all, be careful if you buy a disc conversion kit from one of the companies marketing them. Be sure they understand that you have a '59 Convertible with factory A/C installed. Make sure that they guarantee that their mounting bracket included in the kit WILL push out the 2 stage 8" power booster to the point where it will clear the AC plenum. If they cannot tell you that, then buyer beware..

Howard Prout and I and perhaps a few others now, put our own parts together and built our own system, doing just the front brakes. We did price checking of parts and bought them from the vendor who could supply us the parts we needed at the cheaper price. This whole package of what to buy and how to do this has now been made part of the Paid Membership benefits and is only available now to Paid Members. If you are interested, you can become a Paid Member for $20 for a one year period. Go to the "Donate To Site" button at the top right of this Forum and go through the PayPal procedures. Paid Members have their own Sub-Forum on this Forum..

The dual MC/2 Stage 8" power booster that we bought in chrome from Oid Irish Dave, can now be obtained from others, or you can get them from eBay. See a recent thread on this Forum about that. You may also want to look at this thread...

And this one also.

Thank you both. Do you know if the "member's only" section has a description from someone who has used a kit similar to this?

Thanks

They want $700 just for the parts minus the booster and m/c. You can buy off the shelf parts for much less than that.

Thanks, I love the idea of saving money, however, I don't know yet if I can just purchase the caliper brackets and the booster/MC (that does not interfere with the A/C unit and valve cover). It would be great if I can get just these parts and then purchase the other parts individually without modifications/changes to other parts.


Very few of the "kit sellers" know/understand the A/C situation and tend to be unclear about wheel sizes that will fit.

Thanks

You can get the caliper brackets from Scarebird. To my knowledge he's the only one making them at this time so that's probably where they are getting them.

Thanks, They don't have a phone number so I sent them a message to see if the 14 inch KH spoke wheels will fit.

I know this is a stretch, but just to satisfy my own curiosity why can't the Kelsey Hayes booster be used with a 2 stage master cylinder mounted in place of the original?

Easily convert your classic 1958-60 T-Bird to front disc brake with these brackets. They are AutoCAD designed and CNC laser cut for excellent tolerance then professionally fixture welded for strength and durability.
These brackets use common and inexpensive rotors (1968-69 Mustang front) and calipers (1983-97 S10 2WD) available from your nearest NAPA, O'Reilly's, Autozone etc. or even your local boneyard.


Note that this conversion will require 15" rims. 1975-80 14" Monarch/Granada rims will also work.
