Tech question--

[Greg Reimer 7376]

If I took my '70 Monte Carlo and wanted to race it in Stock, would it be against the rule book to remove the front disc brakes on it and replace them with from drums from a Chevelle? I think the discs were standard equipment back then on the MC, but the Chevelle still had standard front drums until 1972.

i would give tech a call, but i can not see a reason why you could not.

Rulebook says "Must be equipped with stock production four-wheel hydraulic
brake system, or aftermarket disc brakes"

Sounds like to the letter of the rule, if you remove the OE brakes, you must install aftermarket discs.

The next obvious question would be, why?

Greg, I don't know your reason for wanting to switch your disc. to drums, but if it is to get rid of some weight be careful. Many years ago I had a 69 Chevy 2 with factory disc. on the front & was told I could get rid of 40 lbs. going to the drums. Had a friend with a Camaro with front drums, we made a trade I even did all of the work, well the only thing that I lost was time & alot of braking power. I weighed the parts as I was making the switch, the weight difference was nothing, but a deal is a deal & he was a happy camper. My car ran low 10's 130 mph. & it was hard to stop after that switch.

Should be a bit lighter, from my experience..
Also ,less drag
Plus, it's easier to heat and bend the drum brake steering arms for toe-in issues.
Greg, Just do it..Nobody cares (except for maybe a few keyboard racers)

One thing about this whole deal, the discs were all power assist with the big round booster on the fitrwall. Drums either came power or manual. Running a vacuum booster with any kind of performance camshaft would absolutely not work,especially a Stock Eliminator type cam. That would be a weight saver as well.

Drums are “stock production four-wheel hydraulic break system”
