Depending on the year and manufacturing plant of your VW Passat, there could be a uncommon contrastive front braking systems in habitat that Testament vary slightly in procedure. Crack the lug studs loose approximately 1/8 inch, using the ratchet and a 17-mm socket. Lift the Passat, and country the jack stands in a guarded and secure position to device the machine. Remove the lug studs and front wheels.
Remove 1/3 of the brake fluid from the masterly cylinder, discard the fluid and then interchange the cylinder include. Use the parking brake, and allowance the front wheels in an unlocked position so you can modification them when the Passat is elevated.
2. Inspecting the brake manner and purchasing a repair instruction for your particular Passat is always recommended. The CD brake systems on Volkswagens capitalization the corresponding code in hydraulic calipers as any other vehicle on the plan, on the other hand there are slight variations in the tools required that VWs practice to organic the employment.
Instructions
1.3. Inspect the caliper, looking through the front port to determine if the caliper is single piston or dual piston. If the caliper employs dual pistons, refer to the Tips section. There are a few different types of single-piston applications with slight variations in procedure. Look on the outside of the caliper housing for a outboard pad retaining spring. If applicable, use a screwdriver to remove this spring and then set it aside.
4. Locate and remove the caliper guide bolts. Remove the plastic caps to reveal the bolts, if applicable. Guide pin calipers require holding the inner retaining base of the guide pin with a thin-headed, opened-end wrench while removing the bolt with another wrench or a ratchet and socket. A different style caliper may require a 6- or 7-mm hex tool to remove the guide bolt while holding the retaining base. Some caliper applications only require the bottom guide bolt to be removed and then the caliper pivoted upward. Remove both guide bolts and then secure the caliper to the suspension with string to allow easier access to the pads.
5. Remove the pads from the mounting bracket. If the inboard pad is attached to the piston of the caliper, remove that first. Inspect the rotor for scoring or grooves and determine if they should be replaced. Compress the piston of the caliper inward using a caliper retracting tool or a large C-clamp.
6. Clean the mating surface of the mounting bracket and caliper where the pads come into contact using a small wire brush. Be thorough. Remove movable slides and bushings. Apply anti-seize compound to them liberally and replace them. Apply a coat of the compound on the mounting brackets where the pads tabs contact them. Be sure to cover both upper and lower rattle clips, being careful to clean any off that contacts the rotors.
7. Install the new pads by reversing the order. Be aware that uni-directional pads are sometimes used by the VW dealerships and should be installed with the arrow on the backing plate facing downward. Reverse the remaining procedure to complete the reinstallation and then proceed to the other side. Refer to the repair manual for the correct torque specifications on the specific Passat design you are working on when tightening the guide bolts and lug studs.
8. Pump the foot pedal until it feels firm, once the Passat is complete and then lowered back to the ground. Check and adjust the level of brake fluid in the master cylinder with the proper brake fluid.
