Common Brake Repair Uses

• Front left brake drag or uneven pad wear
• Brake fluid seepage at the caliper body or bleeder area
• Soft or inconsistent brake pedal feel caused by caliper wear
• Corrosion-related piston sticking on older brake systems
• Noise or pull during braking from a worn caliper assembly

Installation Notes

Use the OE-specified brake fluid listed on the master cylinder reservoir cap and replace fluid from a sealed container only. Floating caliper mounting pins use silicone grease, and the bleeder screw should be tightened to seal properly before bleeding the system. Verify the inlet and bleeder port size, bracket style, and front left position before installation on your Cadillac Eldorado, Cadillac Seville, Buick Riviera, or Oldsmobile Toronado.
