Volkswagen cars are slightly different from other models. If you're looking to change the brake caliper in your Jetta, you need to see if the caliper uses guide pin bolts or not before beginning. You also need to take into account the importance of the hydraulic line (referred to as the brake line in other cars).
Things You'll Need
- Tire iron
- Multiple various wrenches
- Replacement Jetta caliper
- Bleeder bottle
Lift the car securely on the jack and remove the wheel. If you don't have a jack stand, consult an auto expert to find one appropriate for a Jetta.
Begin to remove the caliper from the hydraulic line from the caliper, but not completely. Remove the caliper from the carrier first by removing the bolts, then remove it from the hydraulic line.
Thread the replacement caliper onto the hydraulic line and tighten it by hand. Fit the caliper onto the carrier, replace the bolts and finish tightening the hydraulic line.
Bleed the system with the help of a bleeder bottle. Connect the bottle hose to the brake bleeder valve, open the valve and use the brake pedal to remove air.
Replace the wheel and lower the car off the jack. Don't test the brakes on the road until you set the pads while stopped. Pump the pedal multiple times until it feels firm.
Tips & Warnings
- If the caliper is connected by guide pins, you must hold the pin in place with a backup wrench while removing the caliper guide pin bolts.
- If you must bleed the brake system through more than one wheel (which is recommended), go in a counter-clockwise path starting with the right rear caliper. Use a different bleeder bottle for each valve.
- Avoid cleaning any brake parts with dry brushing or compressed air, as they may contain asbestos fibers. Run a mist of water over any brake parts, wipe them with a damp cloth and dispose of the cloth in an airtight container.
