[urq] MB brake question

[Johan Hisinger]

Hi Guys, 

I have a small problem, I beg your pardon if this has allready been discussed on the list.

My -88 MB does OCCASIONALLY the following:

last summer on my way home sitting in heavy traffic, only on hot summers days, and even then very occasionally, at first the brake pedal started to feel a bit firm. I had no problem with lack of brake assist though and the pedal travel was normal.

When I got out on the motorway (about 80-100 km/h), and after a few minutes drive the pedal went almost all the way to the floor, before the brakes worked, and at this stage there were no assist on them. I have never had a problem with brakes locking up. 

This happened about 3-4 times during whole last summer, and I drove the car to work every day.

The problem ought not be with the bomb while it is quite new. I cannot remember how many times I can press the pedal before it gets hard, from the top of my head approx. 20-30 times. 

The weird things are that this happened very occasionally and only when it was hot, after sitting in heavy traffic, never during a traffic jam.

Any ideas?

Cheers, 
Johan
