Chevrolet Blazers in 2000 used hydraulic disc brakes to stop the front wheels. This system employs a brake caliper that squeezes the brake pads against the rotor to slow the wheels. The brake rotor is a large steel disc that spins with the wheel. The caliper mounts to the Blazer with two bolts that must be tightened to a specific torque rating to ensure it functions properly.
Single piston calipers have only one sliding rod that engages the brake pad. The mounting bolts for this design must be tightened to 37 foot-pounds.
These calipers have two sliding rods that engage the brake pad. Its mounting bolts must be tightened to 85 foot-pounds. The use of two pistons helps to ensure even brake pad wear.
Some torque wrenches only measure in inch-pounds. To convert from foot-pounds to inch-pounds, simply multiply by 12. For example 37 foot-pounds is equal to 444 inch-pounds.
