LH and RH 1978-Up Metric Brake Calipers
These stock replacement single-piston Metric calipers were standard equipment on 1978-88 GM mid-size cars (Cutlass, Grand Prix, Regals, Monte Carlo, etc.). They feature a 2.375" single piston, shielded bottom inlet, and will save 3-1/2 lbs. per side compared to mid-size 1969-1977 caliper.
- 7/16"-20 inlet
- 5-1/2" Mount Spacing
- Can be used with brake hoses from Pre-1978 GM intermediate cars
Speedway Pro-Lite Vented Brake Rotors, 11.75 x .81 Inch
Every rotor is cast from premium grade, long grain carbon iron which exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.
- Thickness: GM .810"
- Outside Diameter: 11.75"
- # Holes: 8
- Bolt Circle: 7"
- Thread: Thru
- Weight: 8.00 lbs

Proper Break-In Procedure for Steel or Cast Iron Rotors
New steel/iron rotors should be bedded in before being used in racing conditions. Proper bedding will prepare the rotor surface, prolong the rotor's life, and make it more resistant to thermal checking or cracking under severe braking conditions. The following procedures should be performed when bedding in both steel and cast iron rotors. It is best to bed in a new rotor using a used set of pads, preferably ones which will not create heat rapidly. Generating heat too rapidly will thermal shock the rotors. Likewise, when bedding in a new set of brake pads it is best to perform the process on a used rotor. This new/used bedding process permits controlled bedding of each individual component.
Make sure rotor surfaces are free from oils, grease, and brake fluid. Run vehicle up to a moderate speed and make several medium deceleration stops to heat up the rotor slowly. This will help reduce the chance of thermal shock caused by uneven heating of the rotor. Pull into the pits and allow the rotor to cool to ambient air temperature. Care should be taken not to ride the brakes into the pits as this may hot spot the rotor causing premature wear to the surface or structural damage.
NotesThis kit will fit some 15" steel wheels, but not all due to tight caliper clearance. Clearance can be improved with slight grinding of the caliper body, or use of 16" or larger wheels.
