Replace a worn or warped front rotor-and-hub on your classic GM with the Raybestos R-Line Disc Brake Rotor and Hub Assembly 5100R. This front unit combines the disc brake rotor and wheel hub in a single part, providing the friction surface your brake pads clamp against while carrying the wheel studs and hub. It's cataloged as a direct-fit replacement for a wide range of 1967-1974 GM cars (all engines), including the Chevrolet Camaro, Chevelle, El Camino and Nova, Pontiac GTO, LeMans, Firebird and Tempest, Oldsmobile Cutlass, 442 and F85, and Buick Skylark and GS — see the Buyer's Guide tab for the full list of applications.
- R-Line design: part of the Raybestos R-Line, an application-specific line created for everyday driving conditions.
- Integrated rotor and hub: combines the braking surface and wheel hub in one assembly for a direct swap.
- Bolt pattern: 5 lug holes on a 4.75 in (120.65 mm) mounting bolt circle, with five 0.535 in (13.6 mm) mounting bolt holes.
- Rotor specs: nominal thickness 1.035 in (26.3 mm), minimum (discard) thickness 0.965 in (24.5 mm), overall height 3.996 in (101.5 mm).
Signs the original may need replacing include pedal pulsation or steering-wheel vibration under braking, a rotor machined to or below its discard thickness, or deep scoring — diagnose the cause before replacing. These applications use two front assemblies (one per side); this listing is for a single unit, so order two and replace both sides together as a matched set for even, balanced braking. Country of origin: China. Manufacturer part number 5100R.
