How to Replace Front Brake Caliper 01-04 Nissan Frontier

Difficulty: Advanced · About 50 min · Nissan Frontier

Replace a front brake caliper on a Nissan Frontier, using new sealing washers and bleeding the opened hydraulic circuit until no air remains.

Steps

1. Raise the vehicle and remove the wheel

   Loosen the lug nuts on the ground, lift and support the truck securely, then remove the wheel. Keep the reservoir cap closed until you are ready to work on the hydraulic line.

2. Inspect and remove the caliper

   Remove the caliper fasteners and lift it away. If the piston will not retract smoothly with a clamp, the caliper may be seized and should be replaced.

3. Transfer the brake line to the new caliper

   Place a drain pan below the hose connection. Remove the brake-line bolt and discard the old copper washers; install new washers on both sides of the fitting and tighten to vehicle specification.

4. Install the caliper and bleed the brakes

   Secure the caliper and refill with the specified fluid. Bleed the opened circuit with a helper, closing the bleeder before the pedal is released; repeat until clean fluid flows without bubbles.

5. Reassemble and verify pedal feel

   Reinstall the wheel and torque its nuts to specification. Pump the pedal until firm and inspect the hose, banjo fitting, and bleeder for leaks. Do not drive if the pedal is soft.

Check your vehicle’s repair manual for exact specifications and fit.
