How to Fix the Brakes on a '93 Nissan
Removing the Wheels and Tires
- 1). Loosen all of the lug nuts on the vehicle one turn using a lug wrench. Do not loosen the lug nuts any more than one full turn.
- 2). Raise the front of the vehicle. Place a bottle jack under the front subframe. Lift the vehicle and support it with jack stands placed underneath the vehicle.
- 3). Raise the rear of the vehicle. Position a bottle jack underneath the rear axle beam. Lift the rear of the vehicle. Then, support the vehicle with axle stands placed under the rear axle beam.
- 4). Unscrew all of the lug nuts on the vehicle using a lug wrench. Lift the wheels off the lug studs and set them out of the way.
Bleeding the Brakes
- 1). Fill the master cylinder reservoir with fresh brake fluid. Check the fluid level often during this repair and do not allow it to run dry. Doing so will introduce air into the system.
- 2). Locate the brake bleeder screw on the caliper underneath the car on the driver's side front.
- 3). Attach a long length of clear plastic tubing to the brake bleeder screw. Submerge the other end of the hose in a container filled halfway with fresh brake fluid.
- 4). Have an assistant who's seated behind the steering wheel pump the brake pedal a few times and then hold it against the floor. Open the bleeder screw by turning it counterclockwise with a wrench. Allow a little fluid to seep out before closing the screw by turning it clockwise. Then have the assistant release the brake pedal.
- 5). Repeat the step above until fresh, clear brake fluid begins to seep out of the bleeder screw. The fluid should also be free of air bubbles. Be sure to check the fluid lever in the master cylinder reservoir often.
- 6). Repeat the procedure you used to bleed the driver's side front wheel on the other wheels in the following order: passenger's side front, driver's side rear and finally passenger's side rear.
- 1). Lift the wheels onto the wheel studs and then screw on the lug nuts using a lug wrench.
- 2). Lift the rear of the vehicle off the axle stands using a bottle jack. Remove the axle stands, then lower the vehicle.
- 3). Lift the front of the vehicle off the jack stands using a bottle jack. Remove the jack stands and lower the vehicle.
- 4). Tighten all the lug nuts on the vehicle using a lug wrench.
