Installation Notes

Verify rear left fitment by year, make, model, and any listed configuration notes before installation. Inspect brake pads, rotor condition, and brake hoses during service, and bleed the hydraulic system after caliper replacement to remove air from the circuit. Because mounting hardware is not listed as included, confirm reuse or replacement needs before beginning the job.

The unit is assembled with new seals, dust boots made from high-temperature EPDM rubber, and premium silicone lubricant for smoother operation and longer service life in demanding conditions.
