hi all,

I recently went to acura dealer ship for the oil change and was told that my Clutch Master Cylinder is leaking and the fluid is very low. They quoted $375 to repair and refill it. I dont see any leakage under neath my car. Can any one explain me what this thing is and why is it so expensive?
thanks alot,

You can top up the hydraulic fluid in the clutch master cylinder for less than $5.00, if you do it yourself. But the fluid will leak out again, over time. The master cylinder and the piston assembly are both made of metal, but the seals that keep the hydraulic fluid contained are made of synthetic rubber, and shaped like "O" rings. Sometimes a leaking cylinder can be disassembled and only the o-rings need to be replaced. Sometimes the interior walls of the cylinder are scored, scratched, or damaged, and the cylinder has to be machined smooth before new seals are installed.

If the master cylinder fails the brakes won't work.

They don't use second hand master cylinders because the seals may not fit properly.

A set of seals cost about $30. The rest is labour.

How exactly would a failed clutch master cylinder (which is what we're talking about) prevent the brakes from working?

Sorry, didn't read it properly.

You won't be able to get the car in gear.

Sit at a stop light and the cars starts creaping forward, and suddenly you discover it's really`hard to pull it out of 1st gear.

At Saab, back in the 60s and 70s we rebuilt these for $10 in parts and an easy and profitable one hour of labor.
A total of $20, plus tax.. Even if one moves the decimal point....Cars were easier to work on back then...

BTW, the clutch master cylinder probably was NOT leaking, only seeping..
Simply monitor the fluid levels...
