Re: 4 wheel disc recommendations

Not bashing their parts Tom but do not rely on the parking brake holding the car stationary. I have had them before. Also note that the rear caliper bracket does not have any provision for securing the rotor against the rotational force of braking over the centerline of the rotor. They rely on the slide pins for that. It is not that I race or autocross my cars but I do want them to have well engineered brakes since my life and others depend on it. Plus this style of brakes was developed in the mid 70's, there is better technology available.

GM rear disc with the caliper applied e brake. Notice the support for the caliper directly over the rotor. It also stabilizes the caliper when moving on the slide pins.

Re: 4 wheel disc recommendations

I have the KISS kit on my 65 Elky. A-body front discs from a 70 Cutlass (same as Chevelle). Rears are from a 94 Z-28. All are basically bolt directly on to the existing axles. Had to modify the rear E-brake cable brackets - not a big deal, and connect the old to the new brake cables in mid-car. And applying the pressure with a GM hydra-boost from a 1 ton van. Using the pump and reservoir from the same van (dual drainbacl nipples ino the reservoir. Stops with ease and still has feel to the pedal.

Re: 4 wheel disc recommendations

I agree with Phillip 100% on that style of GM e brake being garbage. I didnít even bother ordering my calipers with that set up. I just opted for no e brake for now. I know some of you guys have to have your cars inspected so you have to have one. Or the manual trans guys also. I will eventually change mine out to something with an e brake, but I would like the drum style, that goes inside the rotors. Also I have a Moser rear with Ford ends on it, so I need to find what will work best for me.

Wilwood has a great ID tool on their website to determine what rear kit fits your bearing end and flange stick out. I used their rear discs with internal parking brake on the 9Ē in my Ď72 and couldnít be happier.

Thanks, I have seen that. I will most likely end up with a wilwood setup, just for now I keep finding other areas of the car to throw money at!

Re: 4 wheel disc recommendations

Wilwood, Baer and Kore3 are all good products just a little high priced and usually more brake than most street driven cars need.

I like the sounds of your set up, I have a hydroboost out of a 06 3/4 ton, only problem the square nut is broken, can't seem to find one. I imagine the 94 z's are probably easy enough to find, the early 70's maybe not so much?

As I get older, I prefer complete kits. My Malibu has the Wilwood 4 wheel disc conversion, (Ford ends on the 12 bolt to eliminate C-Clips), and a Hydratech Hydraboost.

The Wilwoods look good with 15 inch wheels.

Re: 4 wheel disc recommendations

I am having my rear drums changed to disc when changing my rear gears. This is the email i received from the shop in regards to installing these brakes:

https://www.summitracing.com/parts/sum-bk1623


"For the rear disk brakes, I really don't like that style of caliper. Getting the parking brake adjustment correct so the piston travel is right, is a really time consuming process. To install them, I would charge $735.00. Now I have a Wilwood rear disk brake kit that has used calipers and brackets, part number*https://www.summitracing.com/parts/wil-140-9315-r The customer changed his mind on what calipers he wanted. They only have 600 miles on them. The rotors are new. I can sell these for $550.00. They will need parking brake cables https://www.summitracing.com/parts/lok-ec-81fu*and brake hoses https://www.summitracing.com/parts/w...odel/chevelle* .

Labor to install this kit is $330.00"
