I'm looking at the Wilwood dual piston set to install. The act like everything you need comes in the kit and I don't see a proportioning valve or restrictor in the kit, but I'll ask.

[left]i bought my kit from Performance Online. Cost $300. Drivers side went on perfectly. Passenger side caliper adapter was way off. I notified the company and have been promised a replacement. Received replacement FedEx overnight.

Did you bench bleed the MC after you had the lines off again? I’ve tried to bleed the MC installed and found that in the vice is the only way. Not sure on the car if you get full piston stroke or not?

Just a thought as to your spongy brakes.

If you don’t have, consider a mighty vac and canister suction gun. I tape the threads of the bleeder screw so I don’t suck air past the threads, and can pull a large amount of fluid through the system in minutes. Have a helper keep the MC topped off with fluid.

What I did first was buy a MC bleed kit. Attach a hose from the outlet back to the reservoir.
What I did next is I made a closed loop. I attached a hose from the left caliper back to the master cylinder and pumped the brakes. Fluid went through the left caliper to the master cylinder. No air bubbles. Using both systems, I assumed I had done a good bleed.

The '65-'82 Corvette disc brake system doesn't need or use a proportioning valve, as the system is front/rear balanced by design due to the larger front caliper pistons and smaller rear caliper pistons, which places about 65% of the braking force on the front and 35% on the rear without using any valves. Are the Wilwood caliper pistons similarly sized front/rear, or are they all the same diameter?

Hello John,

This will be a front wheel disc brake installation only with stock drums on the back. I'm assuming for as long as Wilwood has been in business they have this figured out, but maybe not. I'll check into it and appreciate the heads up. Will the stock 65-82 disc brakes fit the front 62 spindles without a lot of bubba'ing?

rotors fit perfectly on C1 hubs. need mounting hardware for calipers and longer wheel studs.

biggest problem is that you need disc brake wheels to clear calipers

Thanks Bill. Interesting problem. I'm going to take off and retain the stock wheel/tires and go to the 60's style mags to run daily, so I imagine I can order wheels that will fit the big calipers.
