Brake Cylinder Mystery


Wewo

Recommended Posts

Now this problem came along with the clutch slave cylinder when i was bleeding the system. I took the whole rear right brake system apart including the wheel brake cylinder and i cant seem to find anything wrong.

It has some rust stains here and there but there are no deep scratches or dents. But the weird thing is that the fluid leaks from tis component on the brake system.

Any Ideas . . . . .

Just sounds like you need to replace the wheel cylinder - the seals do wear out. I don't know if a rebuild kit is available, but they're cheap, so just replace. Suggest thinking of doing both because if one went, the other isn't far behind and this way you don't waste all that new brake fluid.

Suggest upgrading to the Tii spec wheel cylinder. It is slightly larger and will improve braking a little.

Cheers!

Some advice while working on the brake system in general...

Be *very* carefull threading the fittings back together. They are extremely easy to cross thread, and screw things up badly. When screwing in a fitting you should be able to go quite a bit with your fingers, if you can't you've likely got it cross threaded, back out and try again... It will take many tries on each fitting to get them right, working with the alignment of the flare fitting and the hard lines.

Secondly, use a flair nut wrench. They make them specifically for this purpose so you won't bugger up the soft nut using a standard wrench. Absolutely worth the few bucks it costs for the appropriate wrench.

Hear me now beleive me later... It will be a bit frustrating, but it's soo easy to screw this up. I've seen it done ad. infinitum.

I installed the brake cylinders on Nov. 16 and me and my dad bled the system the day after i installed them. Brakes now have great pressure on the brake pedal.

    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
