D52 Caliper Rear Disc Brake Brackets

[texastrendz]

capt. fab,

i have assembled my rear disc brake kit(d-52 style) and noticed the outer pad is dragging on the rotor hat. is this normal, or should i be concerned? looking at your post of the installed pads it looks like yours are touching as well. is this going to create a singing noise or a vibration in the braking system? thanks again.

Make sure you that you keep the E-Brake brackets.

Can you post some other angles of that? Particularly the e-brake bracket...many thanks!

Did you also put longer wheel studs in?

The assembled brackets shown in the pics were the prototype's. And yes the pads were touching the 'hat' of the rotor. After seeing that issue, I made the caliper brackets 1/16" longer to move the caliper farther from center. This is the first that I've heard of anyone having the pads touching the 'hat of the rotor. I suppose there is a certain amount of variances with different pad manufacturers. I don't know if this would create any noises or issues. Do you have a way to grind down the flange on the pads where they touch?

i resolved the issue by clearancing the contact area of the pad on the caliper itself. i think by grinding the pad i was not resolving the issue. by clearancing the caliper i now can replace the pads without any issue in the future. i only have about .040 clearance. since this is a floating caliper i think it will be fine. i tweaked the mounting tabs of the pads to pull it tight against the caliper not not let is float as much. seems to look o.k. i used a napa brand semi metalic pad.

These look awesome and I will be getting a set in the future. I just want to make sure of one thing. I can use my stock master cylinder and just add an adjustable proportioning valve and they should work fine, correct?

Some guys get away with doing that, but it isn't the correct master cylinder to use. Since you're replacing the rear wheel cylinders with calipers, you need more volume to the rear. So the best master cylinder to use is one designed for a disc/disc brake system. Then you can either install a disc/disc proportioning valve, or install an adjustable proportioning valve in the rear line. The Wilwood unit I posted a pic of above is a nice all in one unit.
