Finishing the brakes on 1987 300D (W124) - replacing master cylinder, brake booster, and bleeding

Replaced the brake booster and master cylinder. Bled the master cylinder in place (versus bench bleed) using the Dorman Master Cylinder Bleeder Kit (part# 14151). Revisited the front brakes - finished new soft line, rotor, and pads on both sides. Then bled the system at each wheel and took it out for a drive!

The replacement temperature gauge LCD I got was from Marcel - you can check out his stuff at www.marceldeijkers.nl/

If the master cylinder leaks does it leak into brake booster

[@bsclifton]

I would say yes. In my case, the seal blew out completely and the reservoir emptied into the brake booster. In a prior video, you can see the damage it did (and all the brake fluid in the booster!)

By the way your front strut is supposed to have that dent. Its for tire clearance .they all have it. My old struts had it as well as new ones.
If you change them be sure to use new foam bump stops and boots.
Struts will last longer. I bought the k.y.b for mine and ride is nice.
Good luck.
