  Q: How to Service and Repair a Brake Master Cylinder on a Left-Hand Drive with ABS on Chrysler PT Cruiser?

  A:

  If your car has a left-hand drive and ABS or not, start by pumping the brake pedal 4-5 times with the engine turned off until the pedal offers a firm press. Take the air cleaner cover and its housing off, unhook the negative Battery Cable and disconnect the power distribution center at the side. On cars without ABS, take the brake tubes off the master cylinder and the proportioning valves and place plugs in all the open tubing. Wipe the surroundings of the master cylinder attachment to the power Brake Booster using a suitable brake cleaner. Unscrew the two nuts at the top of the master cylinder and slide the master cylinder away from the booster. When you have to, unhook the proportioning valves from the master cylinder. Prior to installation, push the brake pedal to disinfect the master cylinder and wipe the booster contact spot. Set the master cylinder on the studs and line the push rod up; push the master cylinder into place until it touches the booster face. After the master cylinder is held in place with tightened nut, attach both ends of the brake tubes to the ports, tightening to 17 Nm (145 in. lbs.). Put on the brake switch wiring, put the power distribution center in its place, attach the negative battery cable again and reinstall the air cleaner housing and its primary cover. Fill the reservoir in the master cylinder until the brake pedal becomes firm and then drive the car. If you don't manage to fix a firm pedal, drain the Brake Lines and check them for damage, then go for a test drive to check the brakes.

  Q: How to Remove and Replace a Brake Master Cylinder Without ABS on a Left-Hand Drive on Chrysler PT Cruiser?

  A:

  With ABS removed from your left-hand drive car, first place the proportioning valves (1, 3) inside the master cylinder and tighten their O-rings to a torque of 27 Nm (20 ft. lbs.). Bleeding the master cylinder is necessary before you install it. Remove the master cylinder from the system and bleed it until the fluid comes out clear. While doing so, wipe from the Brake Booster any cleaner or dirt that could damage its face. Replace or install a new seal on the mounting flange of the master cylinder; if one is already in place, remove it first and attach the new one, so it fits properly without being crooked. If resistance is felt during insertion, put the master cylinder push rod parallel to the booster push rod. Bring the master cylinder mounting holes in line with the power brake booster's mounting studs, then place the master cylinder on the boost. Assemble the master cylinder mounting nuts (3) into the cylinder and tighten by turning them to 25 Nm (221 in. lbs.). If the transaxle uses a manual system and a replacement reservoir is needed, cut the clutch actuator port (3) at the center of the "V" groove (1) and throw out the plug (2) you removed. On the clutch actuator hose (1), slide onto the reservoir port and then fit the hose clamp (2) near the upset bead (3). Link tubes 1, 3, 4 and 5 to ports 2 by the master cylinder and the proportioning valve, making sure the nuts are tightened to 17 Nm (145 in. lbs.). At the switch, insert the wiring connector (2) for the brake fluid level switch, fasten the power distribution center, link the negative Battery Cable and put the air cleaner housing and cover on with the two clips. Top up the master cylinder correctly and test the brake pedal; if it is loose, drain the brake fluid and look for any leaks. Test the vehicle in traffic to check that the brakes are working properly.
