Here's the setup:
Wilwood Dynalite Pro Series Front Hub brake kit
Wilwood Dynalite Forged calipers
Wilwood tandem master cylinder
Wilwood proportioning valve (in rear brake line)
Wilwood 10lb residual valve (in rear brake line)
Stock 9" rear drum brakes.
The Problem:
I seem to have a LOT of brake drag up front. I don't notice it much when I tap the brakes normally, but if I hard stop and then take my foot off of the brake, the car doesn't move again, I have to give it some gas. I think the calipers are locking?
Similarly, sometimes I can let off the gas at about 15mph, and the car will actually slow down to about 5mph.
I have checked the master cylinder, the pushrod is all the way out when no brake is applied. I also have made sure that I have the correct lines in the correct ports. The stock MC has a (F) over the rear port and a (R) over the front, so I figured 'front' and 'rear.' The Wilwood MC says that total piston bore area goes in the rear port of the Wilwood MC, so I put the front brake line there.
I have also tried adjusting the proportioning valve, from full brake to the front, to the least brake to the front, to somewhere about the middle. No luck.
While it was sitting in the driveway and no pressure on the brake pedal, I opened one of the caliper's bleed screws. There seemed to be no pressure in them, because the fluid didn't squirt.
I don't know where to go next. I basically have a car that doesn't like to keep going even when no brake pressure's applied. Any help would be greatly appreciated.
