brake light switch bumper

[rmunson]

A minor but annoying issue is replacing the nylon/rubber bumper on the brake light switch which dampens the brake pedal when it is released.  The original deteriorated and broke into pieces.  I was able to find a hard rubber replacement at Authentic Classics but am having trouble getting it on the end of the switch.  Short of removing the entire switch assembly, has anyone found a trick to this or have other advice?  it is not an easy place to work!  (no surprise)

I could glue to the brake pedal as I have read elsewhere but would prefer to get this bushing onto the switch peg where it will most certainly out live me.

r.munson,

I thought I had replaced mine many years ago. Perhaps it was before this forum came online because I can't find a discussion.  Here's a very old thread that has the NLA part number in the subject.  Perhaps MB Classic is again supplying it?  Can you post a pic of what Authentic Classics sent you?

I bought it at Mercedes 3-4 years ago. No issue with application.

I will check availability when I get to my computer.

I am having trouble getting the part over the protruding end of the switch; it is pretty firm but slightly flexible.

SL Shop in UK has one that has a little different profile than the one from Authentic Classics.  Has a narrower top ridge before the slope.

The one from SLS in Germany also looks like the one from SL Shop and your original part's profile.

I decided to install one of these bumpers on my brake pedal switch... BIG PROBLEM! I was able to remove the old deteriorated orange bumper and was able to get the new black rubber bumper on the end of the switch. everything looked great, no more brake pedal noise when I let the brake pedal go. It used to make a clanging noise like crazy!

I checked the brake lights working fine, everything seemed great. Drove the car around no problem, everything seemed great. 15 minutes on the freeway caused severe overheating and smoking from all four brakes. Brake fluid spilled out all over the engine, and the brakes were red hot.

I took off the rubber bumper, and bled the brakes and everything seems to be ok now but it was a really big problem

The only thing i can think of is that the extra 1/8th-1/4 inch that this bumper added to the end of this switch pushed the brake pedal down very slightly and caused the brakes to be lightly and constantly engaged, which caused them to overheat after driving

My question is is there a way to adjust the brake pedal so that with the bumper on, there is zero brake engagement? my mechanic couldnt figure that out
