This process describes disconnecting the brake *lines* from the rear brakes, not necessarily removing the entire brake assembly. If you need to remove the calipers or drums, that's a different and more involved procedure.
Tools you'll likely need:
* Wrench(es): Appropriate sizes for the brake line nuts (probably 10mm or 11mm, but double-check).
* Open-end wrench or socket wrench: This is often preferred over adjustable wrenches for better grip and less chance of rounding the nuts.
* Socket set: A helpful addition to the wrench set.
* Basin or container: To catch any brake fluid that spills.
* Shop rags or paper towels: To clean up spills.
* Gloves: To protect your hands.
* Wheel chocks: To secure the vehicle.
* Jack and jack stands: To safely lift the vehicle.
Steps:
1. Safety First: Engage the parking brake, chock the front wheels, and securely lift the rear of the vehicle using a jack and jack stands. Never work under a vehicle supported only by a jack.
2. Locate Brake Lines: Identify the brake lines leading to the rear wheel calipers or drum brakes. They're typically metal lines.
3. Prepare for Fluid: Position your container to catch any escaping brake fluid. Brake fluid is corrosive, so be careful.
4. Loosen the Fittings: Using the appropriate wrench, carefully loosen the union nuts connecting the brake lines to the calipers or wheel cylinders. Turn them counter-clockwise. Loosen them a bit at a time, to avoid sudden spurts of brake fluid.
5. Disconnect the Lines: Once loosened sufficiently, carefully disconnect the brake lines. Brake fluid will likely leak out – this is expected, but keep it to a minimum.
6. Plug the Lines: Once disconnected, you'll likely need to plug the open brake lines to prevent further fluid loss. Appropriate plugs are available at auto parts stores. If you don't have plugs, immediately take the vehicle to a mechanic.
7. Lower Vehicle: Carefully lower the vehicle using the jack stands.
Important Considerations:
* Bleeding the Brakes: After reconnecting the brake lines, you'll almost certainly need to bleed the brakes to remove air from the system. This is a crucial step to restore proper braking function.
* Brake Fluid Type: Use the correct type of brake fluid specified for your vehicle. Check your owner's manual.
* Corrosion: Old brake lines can be corroded and prone to breaking. Be extra gentle when working with them.
* Environmental Concerns: Properly dispose of used brake fluid.
Again, if you are unsure about any of these steps, please take your vehicle to a qualified mechanic. Improper brake work can lead to serious injury or death.
