简介
The seals that cover the sensor floats for brake fluid level and the plugs between the master cylinder and the brake fluid reservoir are pretty easy to forget about when they are doing their job. But one day you'll be trying to pressure bleed or flush your brakes and you'll find brake fluid gushing out! Or, you'll find slow leaks of brake fluid when checking your oil or doing other service under the head. Nip this in the bud early on as brake fluid will ruin any paint it touches! The seals are fairly simple to replace, and this guide will help.
你所需要的
-
-
There are a total of four rubber seals that help to keep brake fluid inside of your reservoir during use. When the rubber ages, it can crack, and harden leading to the potential for leaks.
-
The first pair of seals cover the brake fluid sensor floats. They can be easily seen on top of the reservoir. These are very visibly cracked.
-
The second set of seals, also called plugs, seal the area where the reservoir enters the master cylinder.
-
The reservoir is not under pressure when using the brakes so these seals can be in pretty rough shape and still work OK. However, if you bleed your brakes using a pressure bleeder you may find fluid shooting out! That will hint at a good time to change them...

-
Begin by draining the brake fluid from the system.
-
You will need to jack up the car, and remove the wheels. See the W123 guide page for help with both of these topics.
-
Now you can open the bleeder on each caliper to let the fluid drain in to an appropriate drip pan. It will take a while as it will drain slowly. Let it drain until it is barely dripping and the reservoir is empty.

-
Re-fill your brake reservoir with clean DOT4 brake fluid.
-
Then, proceed to bleed your brakes using the pressure bleed method. You can click here for a guide on this process.

After your first drive check for leaks.
