Budget big brake upgrade?

Looking to upgrade the front discs on my 64. Have 70 chevelle discs with a hydroboost setup. The brakes work great, but have experienced overheating / fade and am wanting to avoid that in the future.

Have 2" drop spindles, where would I find brackets / hubs that won't break the bank and allow me to run larger rotors/calipers?

I've thought about just changing out to slotted/drilled rotors but would like go one step as autocross season is coming up.

Anyone running a divorced rotor setup?

Re: Budget big brake upgrade?

Usually fading unless you are tracking your car can be taken care with better pads and rotors. Although some say the 67/68 4 piston brakes were troublesome I do not experience anything except nice stopping power on my 68. Not being an expert with dropped spindles I would try a nice set of pads and rotors first and their are many to choose from. See if anyone here can chime in. Are your rears disc?

Re: Budget big brake upgrade?

Try Porterfield brake shoes and matching pads. Usually the rears need a little more to help the fronts.. I adjust my rear brakes manually, I've found self adjusters leave a lot to be desired.. I use slotted rotors, they work for me...

The fading occurred chasing my buddy through Tail of the Dragon (318 curves in 11 miles https://tailofthedragonmaps.com/tail-of-the-dragon-map/ ). He's setup for full pro-touring, I'm slowly getting there.
Brakes got greasy after a couple miles in, that's the last place you want to lose your brakes. I will be tracking my car as well. I have napa rotors/pads on there now, they work great for daily duties but will be getting more aggressive with the car as autocross season opens up. Rears are still drums but were freshened up when I built the car.

I've seen brackets for the conversion, want to fab my own, but am looking for possibly C4/C5 setup as their rotors are thicker due to larger vanes for better venting. Probably going to source some drum hubs and make plates for the calipers, just need to find a template I can use or go about it myself.

Re: Budget big brake upgrade?

Well you have kinda answered your own question but unfortunately if you want to race then brakes are paramount and saving a buck could cost you your ride or worse your life. 4 wheel disc, pad composition, rotor style and more importantly diameter have to be part of your solution. There are a lot of posts on here with people upgrading to 12 inch rotors and I can tell you first hand my 2014 GT500 had Brembo 6 piston calipers with 15 inch rotors and people complained about fade but to me they were awesome but I didn't track. BTW that's a nice looking car.

Re: Budget big brake upgrade?

Thanks everyone. I'll update if I find anything usable. I have found a bracket template for the LS1 / F-body to A/F/X stock brake bracket.

Just realized I have my stock spindles stowed away, I can easily mock up what I need with no downtime on the chevelle.

Where did you find the template?

Re: Budget big brake upgrade?

It can be a PITA to find cheaper wheels that will clear C5 calipers and fit an A-body, especially a 64-65.

Re: Budget big brake upgrade?

There may be differences between LS1/CTSV, but that template did not work for my C5 fronts on drum spindles. It was close enough though and I traced that to aluminum so I just made my adjustments and a new template easy enough.

No car yet; currently looking for 66-69 project/driver.
