• Nissan Brake Repair: How to Fix Them

    If you own a Nissan, a brake repair might be something you will want to do yourself. Since most cars have front wheel drive, the front disc brakes will usually need service more often than the rear. With just a few specialized tools, a brake repair is not a difficult task and will save you money.

    What You Will Need:

    • Wheel blocks
    • Jack
    • Jackstands
    • Syringe or turkey baster
    • Mechanic’s wire
    • Brake pads
    • Anti-squeak lubricant
    • Torque wrench
    • Brake fluid

    Step 1 – Park Car

    It is important to park your car on a flat and level surface. You need a place where you have comfortable access to the wheel area. Cramped working conditions can make the repair difficult. Engage the parking brake and use wheel blocks or something to wedge the rear wheels from moving.

    Step 2 – Remove Brake Fluid

    Raise the hood and locate the brake master cylinder. Remove the cover, and with the use of the syringe or turkey baster, remove approximately 2/3s of the fluid. Since this fluid will not be reused, dispose of it properly. Replace the master cylinder reservoir cover to keep out dirt and dust from entering. It is also a good safety practice to remove the negative battery lead to prevent accidental starting of the vehicle.

    Step 3 – Remove Front Wheels

    Remove the wheel covers to expose the lug nuts and loosen them slightly. Raise the car using a car jack until the wheel is off the surface. Secure the car by placing jackstands underneath so the car will rest on a suspension cross member. Now unscrew the lug nuts and remove the wheel from the vehicle.

    Step 4 – Disconnect Caliper

    Relocate the caliper by removing the bottom guide pin or mounting bolts. Raise the caliper unit out of the way of the disc. Slight pressure might be needed to compress the caliper pistons. Do not let the caliper hang freely since this can damage the break hose. Use the mechanics wire to secure the caliper in a convenient place. Do not disconnect the brake hose from the caliper unit. Inspect the disc brake rotors. If scored or uneven, remove and have them reground to acceptable levels.

    Step 5 – Remove and Replace Brake Pads

    Brake pads are usually just attached by a compressive clip. By depressing the clip, remove the old brake pads. Install the new brake pads. Apply anti-squeak lubricant on the outside of the pads. Do not apply to the inside of the pads. Attach the brake pad retainers and reattach the caliper unit to its proper place. Use the torque wrench to tighten the guide pin or mounting bolts. Tighten to a pressure of 16 to 23 ft/lbs.

    Step 6 – Replace Wheels and Lower Car

    Replace the wheels and tighten the Lug nuts. Final tightening may be done once the car is back off the jackstands. The lug nuts should be tightened with the torque wrench to 62 ft/lbs.

    Step 7 – Refill Brake Fluid

    First reconnect the negative battery cable. Open the brake master cylinder and add fresh brake fluid to the recommended level. Start the ignition, and press and release the brake pedal a few times until the pressure has built up. Turn off the ignition and inspect brake fluid level. Top off the brake fluid level if low.

    Step 8 – Test Drive

    Road test the vehicle at slow and then moderate speeds to test brake operation.
