Corvette brakes on rear of the 'Chief........


Well,the brake transformation on the rear is complete.I must say it was really simple to do with minimal mod's.The piece that connects the two cables together unneath the body has to be lengthened by about 2 inch's(hence pic)

Good job, have you road tested it yet?

Can you tell us what specific parts you used to make it happen?

Cheers, Mark

It's all Corvette(C3) along with '69 JL8 e-brake cables.What really makes this work is the e-brake cable brackets that have to be welded to the frame.One in the front of the diff,the right side and the other on the rear of the left side of the diff.Another thing is everything is RIGHT hand side.For instance-the e-brake cable levers to actuate the shoes,2 Rights.The e-brake cable brackets that you see that hold the cable you can purchase them on the website"JL8brakes".The inside of the axle flanges HAVE to be radiused(45degrees) to clear the ebrake shoes in order to re-install the c-clips.A real JL-8 axle has the inside edge turned as well.A lathe would do a real nice and more professional looking job.As you can see from the pic's, the ebrake cable connector had to have 2 inches added to both of them.I also used
my hard brake lines with a little coaxing to get them into the calipers.And of course,Corvette wheel studs.When considering wheel and tire size,I found that 15x7(Torque Thrust),as they were designed with the Corvette brakes in mind in '65,and 225 70R15 tire as it has to go bottem first and it will slip into place up inside the wheel well.The car has to be jacked up by the body in order for the wheel to clear the massive calipers which sit on top of the rotor.No getting away from that my friends-believe me I tried every possible configuration and the only one that works is what you see here.I have done alot of research and pre-fitting and now
all I have to do is the front now.I'm now looking for someone who is parting out '68-'82 'Vette as I need the front brake assembly to complete this transformation.No I haven't road tested it yet as I still have some more upgrades I want to do to the 'Chief to make it the only one on the planet like it!!!
I hope all this helps for those who feel brave enough to make such a change to their classic 'B' body.Any questions please feel free to contact me as I may have forgotten something which I'm pretty sure I have.Memory isn't as good as it once was, so please bear with me.Thanks

So it's a trick to get the wheel in over the big caliper... Did you ever try to let all the air out of the tire first? 427Carl gave me that hint.

If you're looking to do a C3 front brake system, If unable to find a complete setup, I've found that you can piece it together part by part fairly economically. It's all available unlike the 67-68 and 69-70 B Body set ups. Also your 66 drum spindle steering arms will work with a small modifiaction to the steering stop. I've seen it all on ebay and some of it brand new, C3 spindles (same as 69-70 B Body), 4 piston carriers, rotors, hubs and even the splash shields. Vette is the best way to go.

When you do the fronts Darren, document it in detail if possible.

I did the 80's Eldorado caliper with 79' TransAm rear rotors. My axle flanges needed a couple thou off to fit inside the rotor hat. The Caliper carrier is a ebay conversion item. The only issue with this setup is the substandard parking brake setup, that and I've yet to find a parking brake cable that will extend all the way up to the caliper. But all the parts were fairly cheap.

Did you try the universal custom fit cables from Napa. cut to size. i used it for my jeep with custom axle on a lifted chassis.

Do you need flex lines to change pads or rotors?
