Anybody do a drum to disc brake conversion in a 1970 chevelle using 1998-2002 camaro/trans am brakes? If so how did it bolt up and was there alot to it? I am interested in this route, just curious who has done this. Thanks

Not a whole lot to it. You need to either fabricate or purchase brackets for the calipers mount up to your spindles,and machine down the outer diameter of the hubs to fit inside of the Camaro rotors.You will also need longer wheel studs along with a set of Camaro brake hoses.If you search ls1 brake conversions,you will find all the info along with a video or two to help you along.You will need at least a 17 inch wheel to clear the new calipers.I have done this conversion on my 66 using the stock drum brake spindles, and would recommend this to anyone wishing to upgrade their brakes without breaking the bank. Pics in garage.

I'm pretty sure that a 16" rim will clear as I had LS1 brakes on a 97 TA that I had and 16" rims for the track. Don't see where there would be any difference from a 4th gen F Body and an A body for clearance. Also , you can clearance the calipers to clear 15" rims.

What about this? would this have everything i would need for a front drum to disc brake conv. in a 1970 chevelle?

Scroll down to the # 16 post as some of the stuff before that might not be so helpful.The information that Phillip provides has some great conversion help that includes using 98-02 Camaro brakes.Not that hard to do either so HTH.

What John said.

I did mine a little different but picked up some better handling also. I Got a 1975 or so Impala set up but only used the spindle and caliper part, have global west offset control arms and 1989 Transam 12 inch rotor. The Impala rotor will not work as they have a 5 inch bolt spacing. It does fit my 15 inch wheels but I do agree above that may be case by case and I think what also helps is I stuck with the old single piston caliper. One nice thing about taller spindles it changes the roll center so the tire has less of a tendency to suck under the car when going around a corner.

Lew, did you do anything about the substantially different length of the steering arm and the height of the outer tie-rod end?

The biggest challenge I had with the swap is the parking brake cables. Not the cable itself, but having compatible ends attached to the cable that connects the F body parking brake backing plates. Finally found someone at a local motorcycle shop to do it. But he bent me over. Charged me $70 for 5 mins of actual labor.

You will need to turn down your stock front hubs on a brake lathe so the F body rotors fit over them. Plus you might need to fabricate new rear brake lines on the axle for rear hoses. I ran new lines on my entire project, so I'm unsure if I could've adapted the existing '67 hard lines.

Other than that, the swap is 100% bolt on.

I did this upgrade on my '66 also installed a master cylinder off a '78 corvette, GM undermount proportioning valve and hydroboost. One of the best upgrades on the car. Stops straight and on a dime.

Lew??

Reviving this thread.
I'm in the process of doing this upgrade on my 64, four drum to four disc brakes. I went to a salvage yard for the calipers. I bought brackets from flynbye for $85 including shipping. I still have a 283 but plan to do a LS engine swap in the future. I think the LS1 master cylinder has a 1-1/8" bore for all wheel disc.

Has anybody made the master cylinder and brake booster work in their chevelle??
Any modifications to the firewall?

I wouldn't bother with the F body booster. Too much work to make it fit. You can mount any master on a stock '64-'66 Chevelle booster. Or better yet, find yourself a hydroboost out of a wrecked Chevy truck. That's what I did.

The Camaro master can be used but the lines come out from the engine side. I used a master from a 2006 Trailblazer SS.

My master cylinder and 11" booster was from Right Stuff. It was intended for a disc/drum setup and had a proportioning valve (PV2) attached beside the MC.

I exchanged that PV2 valve with a PV4 which is for 4 wheel discs.

I was told that's all I need to do. It will be a while before I can road test it.

Before doing all this work try using Porterfield brake pads and shoes.. They made a big difference to the stock disc/drum braking system on my 69 el Camino..
