Brake system for new build opinions
 

Truck: 53 AD, porterbuilt bagged, 9” big new style, 20x8.5 F 20x10R
I’m getting ready to spring for all the parts for the brake system on this build and would like some opinion’s and direction please.
If I ran 13” or 14” front rotors with 12” rear do those of you with experience think I could get away with running a non assist MC?
The reason I ask this is I would like to run the master cylinder under the floor to clean up the firewall. I have to run the Cpp modular or wilwood pro drop spindles. I have been looking at the wilwood 4 piston stuff but it’s at the top and possibly over the top of the budget. Cpp offers a decent looking front 13” kit but their rear kit for the 9” uses a completely different looking caliper.
Any ideas? TIA

The master cylinder needs to match the caliper bore sizes not the rotor diameter. There is almost always more than one caliper that will work on any given rotor.
This web site should help explain

My 2 cents, go as big as you can up front it does 95% of the stopping then just go with a normal size rear. Are something that looks close to the front.:chevy:

I would give Tobin at Kore3.com a call. He sells brake kits from mild to wild. He can also spec out the MC that you will need.
If it's in the budget I would go 14" in front with your 20" wheels. The 14" rotors fill up the wheel quite nicely.
On my 68 C10 I'm running C5/C6 14" front brakes and 1997 Camaro 12" brakes in the back.
