Rear drum brakes occasionally wish habituation moreover to bleeding.
Loosen the bleed screw and monitor the flow into the bottle. When the fluid or bubbles stop flowing, tighten the bleed screw and release the pedal. Repeat the process until you witness no air bubbles escaping the rubber tube for three turns. Monitor the reservoir to make sure it does not drop below half-full at any point during the process. The Suburban's brake development operates identically to nearly all other vehicles in this dignity.
Flush the Brake Lines
1. Remove the brake fluid reservoir cap. Extract any brake fluid from the skilled cylinder and brake reservoir using a turkey baster. Fill the reservoir to the full-line once empty with DOT-3 brake fluid.
2. Stand the filled vehicle off the ground one spin at a age using a jack. Area jack stands under the axle of Everyone rotate after you hog raised the circle and remove the jack. Remove the lug nuts using a lug wrench and allot the lug nuts and tires to the side.
3. Loosen all four bleed screws. Disc brake bleed screws are located on the caliper facing the engine. Drum brake bleed screws are located on the back of the drum above the axle.
4. Have an assistant press down on the brake pedal and hold the pedal down. Tighten all four bleed screws and have the assistant release the pedal. Repeat this process until clean brake fluid is coming out of the bleed screws. Keep the reservoir full at all times during the process.
Bleed the Brakes
5. Bleed the passenger rear brake. Starting at the front just moves the air bubbles around without removing them, so start with the passenger rear and then move to the driver rear, then the passenger front and finally the driver front to ensure all air bubbles are forced out.
6. Place one end of the rubber tubing onto the bleed screw and the other end in the clear plastic bottle partially filled with DOT-3 brake fluid. Make sure the end in the bottle is submerged.
7. Have the assistant press the brake pedal and hold.1993 Chevrolet Suburbans operate a energy brake step that incorporates a brake booster, skillful cylinder and the four sets of brakes to supply stopping gift. All fluids invest in smear and contaminated in day and want flushing. You never simply extract gone brake fluid and refill as you engage in with oil. Instead, you flush the transaction and then bleed the air absent of the process to preserve the Correct levels of strength.
8. Repeat Steps 2 and 3 for the other three tires as outlined in Step 1.
9. Replace the wheels and lug nuts and tighten. Raise each wheel one at a time using the jack and remove the jack stands before fully lowering the vehicle to the ground. Tighten all the lug nuts with the lug wrench once the vehicle is completely on the ground. Top off the brake fluid reservoir and replace the cap.
