How to Replace a Caliper in a Nissan Pathfinder

A Nissan Pathfinder, like most SUVs, is dependent on its brakes. Replacing a worn or cracked brake caliper is not an easy task and is best done by an expert. Talk with one to make sure you know exactly what to do before you take on such maintenance yourself.

Instructions

Removing the Old Caliper

1

Remove the correct tire and wheel assembly once the vehicle is safely raised and supported on the jack stand.

2

Disconnect the brake hose from the caliper by removing the attaching bolt. Plug the brake hose with a small piece of rubber to prevent brake fluid loss and contamination.

3

Remove the support mounting bolts from the caliper. Lift the caliper away from the knuckle to remove it.

Installing the New Caliper

4

Position the new caliper assembly onto the knuckle. Make sure the rotor fits between the brake pads. Install the bolts and tighten them to the appropriate torque.

5

Connect the brake hose to the caliper. Use new washer with the attaching bolt and torque the bolt to 12 foot pounds to 14 foot pounds.

6

Bleed the brake system of air. Open the bleeder valve and have someone else hold down on the pedal to remove the air. Disconnect the negative battery cable before doing this.

7

Use the brake pedal again to test the whole system. Make sure the pads are set and the pedal is firm, and make sure there are no leaks.

8

Reattach the wheel and lower the vehicle. Test the brakes on the road.
