Subject: Clutch Master Cylinder
Posted by David Prantl (more from David Prantl) on Tue, 20 Jun 2000 09:17:11
Spencer,
what you described sounded most definitely like fluid leaking past cylinder seals, in either the clutch master or slave. The car essentially engaged first gear by itself, while you had the clutch pedal on the floor, right ?
It sounds unusual that the clutch hydraulics would stop functioning without any warning. However, if you experienced any inconsistent clutch pedal height and/or pressure in the past, it is likely that these were the warning signs.
Haymill just took the generic approach of recommending a somewhat complete clutch job. This is not an unreasonable way to solve the problem.
If your clutch works smoothly and consistently now, then I would say that Newbury did a good job, and saved you some money too. You see, a more frugal approach to fixing a losing-pressure clutch is to change the master cylinder, and see what happens, before tearing into the whole clutch. This is exactly what they say they did.
Just for clarification, the master cylinder is above the clutch pedal, whereas the slave is at the center of the clutch assembly. The master can be changed without removing any other components, but the slave can only be changed by removing the entire clutch assembly from the car.
It seems only natural for a tech to want to 'enjoy' your turbo convertible for a couple of hours, especially if it was a warm and sunny summer day ! I wouldn't be terribly happy about it, but if they fixed the clutch, without buggering up anything else, I'd use them again rather than going back to Haymill. You might point out next time that you don't appreciate their employees using your vehicle for personal business while it is at the shop for service. Drop it off and pick it up yourself, ask that they keep the 'test' drives at less than 10 miles, and keep an eye on the odometer. To verify consistent clutch operation, the car does not really have to be driven even 1 mile.
Best of luck.
