Power Stop's Autospecialty Stock Replacement Brake Caliper is engineered to restore factory-fresh hydraulic force and clamping performance without breaking the bank.
When maintaining the precision braking balance of your chassis, leaving old, contaminated brake calipers in place is a recipe for uneven pad wear, soft pedal feel, and reduced track or street performance. Power Stop's Autospecialty Stock Replacement Brake Caliper is engineered to restore factory-fresh hydraulic force and clamping performance without breaking the bank.
Rebuilt with relentless attention to detail, these calipers undergo a strict remanufacturing process to guarantee optimal piston actuation. Complete with a fresh mounting bracket, premium seals, and hardware, this unit drops directly into your stock setup. It is the ideal choice for enthusiast restoration projects, daily drivers, or winter beaters needing clean, dependable front-end braking strength.
Key Features:
Replaces sticking or degraded stock calipers to re-establish proper hydraulic pressure.
Thoroughly batch and pressure tested to guarantee safety and leak-free operation under heavy braking.
Upgraded high-temp EPDM rubber seals for enhanced thermal endurance.
Premium synthetic silicone lubricant prevents pin binding and ensures even pad wear.
Refreshed stainless steel hardware prevents corrosion-related pad drag.
Fully assembled with pre-installed hardware and mounting bracket for minimum downtime.
