This, of course, only applies to those smart enough to have bought one of these cars with a stick shift! What MB were thinking mating these 616/7 engines to an A/T box is beyond my ken.

The method of pressure bleeding from the front brake caliper is most unsatisfactory for a number of reasons:

a) You are filling the clutch system with dirty fluid from the caliper.

b) As the front of the slave is inclined upwards on level ground (much worse on ramps) an air bubble is trapped at the front of the cyl. not purged when bleeding and can remain there giving a soft low pedal.

c) The whole procedure is a time consuming P.I.T.A. and you need an assistant.

There is a much easier and quicker way to R & R and bleed the slave cyl.

1) Remove clutch feed pipe from brake M/C and drain reservoir. Replace feed pipe and refill to max with new fluid.

2) Remove pipe from slave cyl. and cap the pipe end with one of the bleed nipple rubber cups.

3) Undo bolts and remove slave.

To re-insall:

1) Thoroughly bench-bleed the slave leaving the push rod fully extended. Ensure all bubbles are out and fluid is filled level with the top of the pipe connection.
2) Remove the rubber cup and let at least an egg-cup full of fluid drain down to replace old fluid in clutch M/C and then tighten pipe connection.
3) As the piston is pushed back as you bolt the slave back on any air in the pipe is pushed back thro the M/C.
4) Top up the reservoir and you’re done!

The system is self-bleeding anyway but the trick is to get all the air out of the slave piston.
