1995 c1500 SBC 350 2WD single cab short bed.
Id like to upgrade my front brakes/caliper... ...I’d like to know what size brake rotor and caliber would I be able to run(big brake kit)?
I don't know of any larger-diameter rotors beyond what GM offered on the 8-lug trucks, although the aftermarket may have something for the 5-lugs. You could check catalogs for the usual suspects--Wilwood, SSBC, and so forth. Try to avoid companies selling counterfeit crap direct from Communist China.
Keep in mind that the larger problem with the typical 1500 brakes is in the REAR, not the front. You almost certainly have the JB5 brake code. JB5 254mm leading/trailing shoe drum rear brakes are a fookin' tragedy.
Do you have the usual 1500 "Ten bolt" axle? Given the larger tires, you're gonna need a bigger/stronger rear axle, in a steeper gear ratio. The C2500 6-lug 9.5" rear axle seems to be less-common than the K2500 6-lug unit; and either you need different axle shafts, or you need six-lug wheels. The good news here is that the C2500 axle should have the much-superior 11.x Duo-servo rear drums.
There is a small chance you have JB6 brakes, and the 14-bolt semi-float axle already. If so, all you need is deeper gears.
Without a strong axle, bigger brakes, and steeper gears, you're gonna really regret bigass tires.
For fukk sakes, DO NOT spend money for a craptastic flat-bracket "rear disc conversion" kit.
Brake parts I have also bought include NBS master cylinder
Make damned sure you are not using low-drag calipers uup front (or in the rear) when this project is complete. In addition, the larger-diameter master cylinder bore is going to increase the pedal effort, perhaps
dramatically if the power booster fails.
and a Wilwood proportioning valve.
So you're discarding the ABS unit? Probably not a great idea.
