Hi Forum Members,

For the following cars, that have a Hydraulic brake servo booster.

e28,533,535,m535,m5;
e24,633,635,m635,m6,L6;
e32,735,750;
e23,728,730,733,735,745;

This Do It Yourself (DIY) is to re-build the Brake Servo Booster # 34331156925.
On the e23 it is part # 34331152825. The e23,e24,e28,e32 735 all of the 10 piece interior repair kit are identical., for both part numbers.

The e32 750 has a different part # 34331161772,
It uses a shaft seal instead of an o-ring at the firewall end. And is slightly more expensive.

I recently rebuilt another hydraulic brake servo booster, and I was amazed at how the rubber o-rings were deformed.
They are now an oblong shape. The large o-ring 38.0mm x 3.0mm, at the front of the booster. It now measures 2.55mm high instead of 3mm.
And is 3.28mm thick, were it should be again be 3.0mm. And it is noticeably more brittle. The smallest o-ring was brittle and it broke when removed.
