Brake Service Details

This caliper is intended for Infiniti Q45 front left brake repair where the original unit is leaking, sticking, corroded, or no longer holding proper hydraulic pressure.

The 99-00605A is a practical replacement when the original caliper body, piston movement, or bleeder hardware has deteriorated.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Brake fluid leakage at the caliper body or bleeder screw
• Uneven pad wear caused by a sticking piston or slide hardware
• Reduced braking performance from a seized front left caliper
• Corrosion on the original cast iron caliper housing
• Brake drag or pull during stops on the Infiniti Q45

Installation Notes

Verify the front left position, inlet thread size, and banjo bolt connection before installation. Inspect brake hoses, pads, and rotor condition during service, and bleed the hydraulic system thoroughly after replacement. Confirm bracket cast number 588 and housing cast numbers 38, 28, or L only as reference points during part matching; always rely on the vehicle application and brake system specifications. Part number 99-00605A should be matched to the listed Infiniti Q45 fitment before installation.
