Clutch Master and Slave Cylinders


Recommended Posts

If the cup was still available separately, Tom, you'd be in business for $2.95...

 

that's almost always what wears out.

I'll give you $2.95 for the rubber cup ; )

 

When I bought my replacement, I followed someone's advice on here and ordered a heim joint, to replace the bit that broke on yours.

It is in the parts bin, since I could not see how to make it fit.

I now disagree with some of the timing advice I have given in the past.  I misinterpreted the distributor curves in the Blue Book. 

I've switched from using ported-vacuum to manifold, with better results. 

I apologize for spreading misinformation.

Well, the pedal went to the floor a little too easily this morning.  Another pump and it worked as it should.  It did this twice though and the fluid level is high enough to feed it, so the car is now up on stands.  I will be installing the one I cleaned up earlier in this thread and dissecting the one that is leaking now.  Maybe the 'cup' Toby mentioned above is torn. (?)

 

So... remove the driver's seat, pull off the pinch welt, peel back the one piece carpet and let the fun begin!

Heh, I guess I got distracted... I never did the swap.

The good news is that the master cylinder has stopped leaking.

Apparently, it healed.

:)  WIN  :)

My clutch leaked at the master and slave when I got my car and it took me awhile to get around to fixing them, so I got used to keeping an eye on that reservoir.  It warms my heart to see it staying full again.  There was one incident when the pedal went to the floor, recently, and made a funny liquid squirty noise.  The next pressing was normal and it has been fine ever since.  

 

I am currently in the process of bleeding the clutch/brakes.  The pressure bleeder is connected and the car is in the air.  Time to crawl under and have some fun.

 

EDIT:  I should have just continued this thread, but instead, I started a new one.  Here it is:

The bore on the ATE master I cleaned up continued to rust while being stored.  As seen in the link above, I used the internals from the old one in the body of the new one.  So far so good.  Fingers crossed.

I just repaired my clutch master cylinder this morning.

Same issue, a very slow leak into the pedal box...just enough to annoy me!

Could not find a clutch master repair kit...only complete assemblies.

So, I cleaned the gunk out, and the cylinder wall was perfect. I expected to see corrosion on the bottom, since this is a low spot where water can collect.

Checked and cleaned everything, the rubber seals looked OK, so I just reassembled and pressure tested. No more leak. Let's see how long this will last.

PS: No need to remove the driver's seat or pull back the entire carpet. Just pull it back enough to get a wrench in between the brake and clutch slots in the carpet pad.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
