Default C-1 disc brakes

Who offers a good disc brake kit for 57-62 Corvettes with stock chassis and suspension? Good quality and value.

Thanks,
Rex

Performance online. Just bought the kit. Super easy to install. Everything you need is included. Here is a link:

If you are keeping the stock original master cylinder, you will need to remove the residual pressure valve from it. Easy enough to do it, if you rebuild the M/C.

Otherwise, your disc brakes will drag. Drum systems have the shoe springs to keep them from dragging, but more modern calipers do not (more modern relative to C2/C3 calipers).

I went with the kits from Wilwood. They include everything you need and was easy to install. They look and stop great. They are kinda pricey but, I kept an eye on eBay and was able to find front and rear sets being sold by people that bought them for their cars and never used them. Got the rear set for $650 and the fronts for $700 (red calipers). For now I just rebuilt the stock master cylinder without the residual pressure valve and it works great.

I run 15” Torque Thrust II wheels and had enough room for the 12.19” disc. Gives me a little more stopping power over the standard 11” kits out there.

I used a kit from Master Power Brakes, that included a dual master, on my 62. The price was good,installation easy and I have been very satisfied with them. I installed them 2 years ago and have driven close to 40K miles with no issues or regrets.

there is a difference in what what calipers are used in various kits, so check...

when i first put discs on mine i used oem 4 piston corvette calipers and rotors on the original C1 spindles with the oem C1 M/C. but OEM calipers seem to have fallen out of favor nowadays

the biggest problem at the time was wheel selection, i had to use corvette disc brake wheels for caliper clearance.

I just bolted a kit to my 60, didn't touch the master, yet. Seems to work fine, sure stops better. Ran it that way all last summer.

I converted my 1960 to front disc brakes (non power) with the ECI Brakes kit for early Corvettes.

http://www.ecihotrodbrakes.com/early...nversions.html

Prior to the disc brake conversion I had already replaced the single master cylinder to a dual unit from Master Power Brakes unit for a C1 Corvette...

I'm preparing to convert my 59 to discs. Where is the residual pressure valve on the original M/C?

Mine did not come with one. I added them from MPBrakes inline 2/10 lbs:



https://www.mpbrakes.com/pc_combined...yword=residual

Kit from MP brakes which has dual master cylinder.

Bill where did you find the kit to mount the corvette calipers?

It's right behind the outlet fitting on the front of the original master cylinder - see photo below.

Is the original 57 master cylinder with this modification adequate for disc brakes?

Thanks,
