Product Details

DuraGo has spent decades supplying aftermarket brake components through ISO-certified manufacturing. The BR5551 follows that approach with attention to fit, form, and function for rear brake service on 1982-1987 Chevrolet Camaro and 1982-1987 Pontiac Firebird, plus 1988 Chevrolet Camaro rear and 1988 Pontiac Firebird rear except performance package models. This rotor cross-references Monroe Shocks & Struts 5551 for the same application.

What This Rotor Helps Address

• Brake pulsation from worn or uneven rotor surfaces
• Reduced braking consistency from rotor thickness loss
• Noise caused by surface irregularity during pad contact
• Rear brake service needs on Camaro and Firebird platforms
• Replacement of a vented rear rotor with the correct bolt pattern and dimensions

Installation Notes and Tips

Verify rear axle and brake package details before ordering, especially on 1988 Camaro and Firebird models that exclude the performance package. Confirm rotor dimensions, bolt circle, center hole diameter, and discard thickness against the original part before installation. Clean the hub mounting surface thoroughly and inspect pads, calipers, and hardware condition during brake service.
