Below is an analysis using the Brake Torque Calculator found on Pro-Touring.com. This calculator will give you an idea of what brake torque is for a certain front and rear setups. I am just going to show the changes from the stock front g-body brake system and compare them to a Blazer dual piston brake swap, a stock LS1 Camaro brake swap, a LS1 Camaro brake swap with Corvette calipers

This entire post is a really good read if you are interested about brakes.


Here are the inputs that are the same for ALL different types of brake systems shown below.
6 to 1 pedal ratio
26 tall tire
100 ft/lb pedal pressure
Manual Brakes NO POWER ASSIST
Pad Coefficient of Friction - .45
Use of stock type (tandem) master cylinder

Stock Blazer Twin Piston Front Brake System
NOTE: The Blazer twin piston front calipers have a piston area too large to run a .875 bore master cylinder. These calculations are using a 24mm bore master cylinder.
Rotor Diameter 10.75
24mm Bore Master Cylinder Area - .701 sq-in
Line Pressure 856 psi
Front Caliper Piston Area 5.152 sq-in
Front Clamping Pressure 4410 pounds
Front Rotor Torque 889 ft/lb
Tire Forces 821 lb

Stock Blazer Twin Piston Front Brake System
NOTE: The Blazer twin piston front calipers have a piston area too large to run a .875 bore master cylinder. But to show the differences between the systems, these calculations are using a .875 bore master cylinder.
Rotor Diameter 10.75
7/8 Bore Master Cylinder Area - .601 sq-in
Line Pressure 998 psi
Front Caliper Piston Area 5.152 sq-in
Front Clamping Pressure 5142 pounds
Front Rotor Torque 1036 ft/lb
Tire Forces 956 lb


Rating from best to worst:
1. LS1 Camaro / Firebird stock front brakes with 7/8" bore master cylinder.
2. Blazer Twin piston stock front brakes with 7/8 bore master cylinder. NOTE: This setup will not work with a 7/8 bore master cylinder.
3. LS1 Camaro / Firebird front brakes with Corvette brake calipers and a 21mm bore master cylinder. NOTE: A 21mm master cylinders are fairly rare and hard to find.
4. Stock g-body/S10/3rd Generation F-body stock front brake system with 7/8" bore master cylinder.
5. LS1 Camaro / Firebird front brakes with Corvette brake calipers and a 7/8 bore master cylinder.
6. Blazer Twin piston stock front brakes with 24mm bore master cylinder.
