The caliper on the 1994 Nissan Sentra uses hydraulic coercion to shut a piston, located inside the caliper. As the piston closes, the brake pads inside the piston grips the brake rotor and stops the Sentra. The most possible constituent of a brake caliper to fracture is the piston. Due to the manufacturing method of the brake caliper, it is easier to moderate the complete caliper than to alter the piston.
Instructions
1. Loosen the lug nuts, using the tire iron, supplied with the Nissan. Distance a jack under the frame, and jack the vehicle aerial Sufficiently to distance a jack stand under the frame. Lower the Nissan onto the jack frame. Remove the lug nuts, and pull the turn off the vehicle.
2. Ajar the engine hood, and remove the cap from the proficient cylinder.
3. Direct the bleeder valve on the late brake caliper, using a wrench.
4. Fill the advanced brake caliper with DOT5 brake fluid, using the threaded gap for the brake string. Hang in to fill the caliper, until the brake fluid comes outside of the gap in the bleeder valve. Quick the bleeder valve, using a wrench.
5. Loosen the brake contour, connected to the top of the experienced caliper, using a wrench. It is common for brake fluid to flow from the bleeder valve. Clean it with a towel.12. Close the master cylinder cap, and then close the engine hood.
7. Remove the two bolts that secure the caliper to the axle meeting, using a socket and ratchet. The bolts thread into the caliper from the back of the axle meeting.
8. Pull the decrepit caliper off the rotor and remove the brake pads from the caliper. The pads simply rest inside the caliper, as they accomplish not bolt in assign.
9. Compass the antiquated brake pads into the inexperienced caliper. Whether you applicability modern brake pads, applicability original rotors, besides, as the pads wear into the rotors, and just out pads Testament not wrinkle up equitable.
10. Remove the wire tie from the au courant caliper, and slide the caliper over the brake rotor. Secure it into habitat, by threading the two bolts through the back of the axle assembly into the caliper. Tighten the bolts with the socket and ratchet.
11. Bleed the air out of the brake caliper. To do so, open the bleeder valve, using a wrench. Have a second person press on the brake pedal. While he continues to push the pedal down, close the valve. Have the him let off the brake. Repeat this procedure, until you have full brake pressure, when pushing down the brake pedal. Remove the brake line from the caliper, and thread it into the threaded gap on the brand-new brake caliper.6. Hang the contemporary caliper onto the front spring, using a wire tie. Achieve not spare the recent brake caliper to hang off the brake limit.
13. Spray the brake rotor with brake cleaner to remove any grease or brake fluid from the rotor.
14. Place the wheel back onto the Nissan; thread the lug nuts onto the wheel studs, and lightly tighten the lug nuts with the tire iron.
15. Remove the Nissan from the jack stand; lower it to the ground, and tighten the lug nuts with the tire iron.
