    disc conversion kits

    Classic Parts of America Chevy Duty) has provided the lion's share of parts for my 54 truck but I've used Classic performance parts for some specialty items. Scroll down the page and you'll see they offer the bracket kit with spindle spacers and the correct seal for the conversion.

    Check out their site and make your own decision. Just another option.

    Thanks, Dave

    Good to know. Thanks for the site.

    I only wonder what the weight difference is between a Camaro and a 3/4? Would these Camaro disc brakes be able to safely and continually stop a 3/4?

    I would say yes.If those old band brakes will stop it then disc should stop it no problem. There is alot more clamping force with disc and no fade.

    disc brakes

    Re: Disc brakes on pickup trucks.

    Personally, after setting up pickup trucks with rear disc brakes....I wouldn't do it again!!! Especially when you're using a power boosted system. They just work TOO well!! And that's where you wind up getting into trouble. Even with an adjustable proportioning valve, cranked down to restrict rear brake lock-up; it's the reason why modern vehicles are mostly all ABS controlled.

    With the weight distribution of a pickup as it is....front discs are great....I prefer manual discs, but boosted front discs with drums on the rear works fine if you are paying attention during heavy braking situations. The disc/disc boosted system is going to require getting your adjustable proportioning valve tuned after doing some experimenting to get your bias dialed in. Toss in a power booster and the situation gets even more touchy. Here's what I've discovered.

    During normal driving you won't have any real issues. However, during heavy braking, the driver, even strapped in securely, has a tendency to apply more pressure on the brake pedal as your body moves forward. Unless you can back off on the brake pedal you're going to naturally apply more pressure on the brake pedal. Once you lock up your brakes, control is going to be an issue. The modern abs system compensates for this extra pressure. You don't have to pump the brakes to maintain steering control. With the non-abs system, you old truck becomes the "mass" factor in an equation that can yield unpleasant results.

    For that reason, I no longer run rear discs on the old trucks and prefer manual disc/drums on a non-abs situation. I can dial down my rear bias from the cab of my truck on wet pavement to all but eliminate rear-wheel lockup.

    IMO, a good set of drums brakes in the rear will suppliment front discs and give you a much better brake control. That's my story and I'm sticking to it!!!

    rear discs

    I agree on the rear drums. I am running 4 wheel power discs, and have no issues, however, they will stop right now. I am considering going to a smaller booster to help. Rear disc brakes are a major overkill on these trucks unless you are hauling heavy, or trailer towing. One thing about 4 wheel discs...they look sweeeeeeeeet! So if you are running custom rims, that will show the brakes, I like them! Just my 2 cents worth.....................Mike
