Detailed Description

DuraGo manufactures aftermarket brake components through ISO-certified factories with attention to fit, form, and function. The BR5530 follows that approach with a vented rotor and integrated hub assembly for front brake service on 1978 Buick Century and Regal, Chevrolet El Camino, Malibu, and Monte Carlo, Oldsmobile Cutlass, Cutlass Calais, Cutlass Salon, and Cutlass Supreme, plus Pontiac Grand LeMans, Grand Prix, and LeMans. This part number, BR5530, is a direct replacement choice for vehicles that use the specified 5-stud, 7/16-20 hub and rotor configuration.

This part cross-references Monroe Shocks & Struts 5530 for the same application.

Common Problems This Part Can Address

• Front brake rotor wear that has reached discard thickness
• Hub and rotor service needs on listed 1978 rear-wheel-drive platforms
• Brake pulsation caused by uneven rotor surface condition
• Noise or vibration related to worn front rotor/hub components
• Service replacement for damaged or corroded brake rotor and hub assemblies

Installation Notes and Tips

• Verify vehicle fitment by year, make, model, and front position before installation.
• Inspect bearings, seals, and related front-end components during service.
• Clean all mating surfaces and confirm proper torque on wheel studs and hub fasteners.
• Check rotor thickness and runout after installation to confirm brake system condition.
• Because this assembly does not include an ABS tone ring, confirm the vehicle does not require one for the front application.
