Installing a skilled cylinder is usually a two-person business. This method is used to play down the risk of any air remaining in the brake lines. Regardless of the manner, these lines are opened and removed in adjustment to alter the evil item. Air Testament enter the lines and it must be removed.
Instructions
1. Remove the brake fluid lines from the adept cylinder. The lines are held in situate by speciality nuts that authorize the fluid tubes to pass concluded their centre and chalk up threads on their outer surface. These nuts hold far less structural sincerity than a peanut with inner threads that tighten against a solid bolt. The fury a criterion, open-end wrench applies to these unsupported nuts is in two places---not Sufficiently to successfully obtain the devotee and loosen it. A wrinkle wrench, designed for this location, slips over the wrinkle then onto the kernel, gripping it in six places instead of two. Unless a limit wrench is used, the aficionado Testament round over and be bothersome to loosen.
2. Remove the two mounting bolts holding the adept cylinder in country against the firewall. Wrap the masterly cylinder in debilitated rags to absorb any brake fluid that Testament leak away. Brake fluid is bare damaging to paint and leaves a stain that cannot be buffed out.
3. Bench bleed the master cylinder. Mount the new master cylinder in a shop vise, remove the filler cap and add new brake fluid. Mount the body of the master cylinder as level as possible to prevent air pockets developing when new fluid is added. Wrap the tip of a large Phillips screwdriver with a shop rag and press it against the valve end of the master cylinder. Lean against the screwdriver, using body weight to push the valve in and out several times. Fluid will spray out of the line ports. Use a shop rag to contain the spray.
4. Install the new master cylinder. Fasten the two mounting bolts and install the brake lines. Use caution and do no cross-thread the line nuts. Start each one by hand and make sure they are perfectly aligned as they are tightened.
5. Bleed the brakes. Have an assistant lightly pump the brake pedal, then hold steady pressure against it. Open a bleeder valve at the right-rear wheel. Close the valve after the assistant states the break pedal is completely depressed to the floor. Tighten the valve and repeat the process of lightly pumping the brake pedal and holding pressure, opening the valve to remove the air while the brake pedal goes to the floor and closing the valve. Do this at each wheel in the order of distance from the master cylinder, the right-rear being the most distant, followed by the left-rear, the right-front and finally the closest, the left-front. Once the chunk has been installed on the van, it Testament be needed to bleed the brakes of air pockets that evolve when the development has been opened. This requires specialized Accoutrement or an assistant. Indivisible steel brake lines are routed from the skillful cylinder to the front and rear brakes. Some systems handle four seperate lines, while others applicability two lines that split to serve the left and correctly front and the left and correctly rear.
