Detailed Description

Nugeon 99P17683B is a remanufactured front left disc brake caliper engineered for 1999-2004 Jeep Grand Cherokee models listed in the fitment data. The TechShield 360 (tm) product line focuses on corrosion resistance and service-ready brake hydraulics, making this caliper a practical OE-style replacement for vehicles that need restored clamping performance and consistent pedal response.

The caliper uses a cast iron body, two phenolic pistons, and a rust-preventative finish to support long-term brake service. It includes the bracket, bleeder screw, caliper slides, dust boots, and brake pad installation hardware where applicable. The inlet uses a banjo bolt connection with a 3/8-24 thread size, and the bleeder screw uses M10-1.0 threading.

What This Caliper Helps Address

• Uneven or reduced braking at the front left wheel
• Sticking caliper movement caused by worn slides or seals
• Brake fluid seepage at the bleeder or inlet connection
• Corrosion-related caliper replacement needs
• Brake drag or poor pad release from a worn hydraulic assembly

Installation Notes and Tips

• Verify front left fitment against the vehicle year and brake configuration before installation.
• Inspect the brake hose, banjo bolt sealing surfaces, and copper crush washers during service.
• Bleed the brake system after installation to remove air from the hydraulic circuit.
• Check pad wear, rotor condition, and slide movement before returning the vehicle to service.
• Confirm the bracketed application matches the original caliper design on the Jeep Grand Cherokee.
