I’m new to the Chevelle family and I’m looking for some helpful advice. I would like to upgrade my 68 Chevelle manual drum brakes to four wheel power disk brakes. I enjoy hitting the local junkyards to find a deal or two, but I’m a little unclear what to look for when it comes to breaks. I have done a little research, but still have some questions on what car models and years will bolt onto my 68. In addition, should I look for different years and models to obtain heavier duty spindles and rotors? Does it matter? I will start with the front brakes. What I have learned is that I can use the front disk brakes off of 64-72 GM A-body cars which are the following Lemans, Tempest, Chevelle, El Camino, Monte Carlo, Skylark, Grand Sport, Cutlass, and 442. Is this correct? Would these be a bolt-up solution or would they require some modifications?
When it comes to rear breaks I was told you can use a mid 90’s rear disk brake off a Camaro (92-96 I think).
I understand that I will have to match this system with the correct proportioning valve, master cylinder, and booster.

Thanks in advance for all the support and help.

Looks to me like you have it all the info.

Just make sure you get the right proportioning valve,either a factory type or a new type to adjust for the front disc/rear drum setup.

No mods are needed to fit 68-72 a body brake parts. One thing i can suggest though is that you get a Hollander interchange manual.

Have fun and welcome to the club.

Where are you from?

One little tidbit of info that'll help is when converting to discs using the stock setup use '69 Camaro disc brake line hoses. They are an inch or so longer, and will work with the stock mounting location that drum brake cars had on the frame.

Also do a search for "B-body" or "tall" spindles and you'll see one of the most common alternatives to the stock spindle. Some argue that it causes bump-steer problems, but most will agree that it really optimizes the suspension for cornering AND braking. Only real problem is the cost of tubular (or adjustable) upper control arms required to make it work.
