Product Details

Nugeon part number 97P17859A is a rear right disc brake caliper for vehicles that use a 3/8-24 inlet thread and banjo bolt connection. The remanufactured cast iron housing is finished with a rust preventative coating, and the steel piston is paired with dust boots for brake system service. This caliper is a practical replacement for rear brake hydraulic repair on 1995-2004 Ford Explorer and Ranger platforms, as well as 1997-2001 Mercury Mountaineer and 2001-2002 Explorer Sport and Explorer Sport Trac models.

TechShield 360 identifies Nugeon’s product line for brake hydraulic components, and this caliper follows the specified OE-style fitment and hardware configuration for the listed rear right applications. Part number 97P17859A is also a useful reference when sourcing a direct replacement for the same brake position on these Ford and Mercury vehicles.

What It Helps Fix

• Rear brake drag caused by a sticking or seized caliper
• Brake fluid leakage at the caliper body or bleeder area
• Uneven rear braking on Ford Ranger, Explorer, or Mountaineer applications
• Corrosion-related caliper wear on older rear brake systems
• Brake service issues tied to worn piston seals or damaged dust boots

Installation Notes

Verify rear right placement, inlet thread size, and banjo bolt connection before installation. Transfer or install brake pads separately, since pads are not included. Bleeder screw, dust boots, and brake pad installation hardware are included; bracket, slides, and anti-squeal shims are not included. Use the correct copper crush washers where applicable and bleed the brake system after installation.
