Brake Pedal Excess Travel

[mazzo]

Just got through the MOT yesterday without a hitch and then today when I was progressively braking, the pedal kept going down.

 

Pumping it brought it up again - and when braking normally it is OK. It is the slow gentle braking at low speed where the pedal sinks.

 

Any ideas?

Sounds like your losing the vacuum while the pedal is under constant use if the short application of the pedal is ok? check all the hoses to the servo for splits and leaks? check the operation of the one way valve?

there are a couple of posts on the topic of so called dodgy brake pedal habits and there are a few different opinions on what is an acceptable standard! if you think yours if dangerous get it check out ASAP

Thanks for that.

 

I did read the other posts (especially the one with the differing opinions!) but mine doesn't fit their description. It has always been "normal" without excessive travel and even now sudden, non-progressive low speed braking is absolutely fine.

 

Did the tests. No engine running, pedal hard - no progressive travel. Start engine with foot on brake and it goes down - but again - no further travel.

 

I may be getting paranoid, but I can hear a whooshing sound as I press the brake. It comes from the pedal area. It might have done this before - but I've not noticed it. Then again - I've never listened before!

 

I've had the car nearly 2 years and it has never done this before.

 

There's a little niggle in my mind that the brake test in the MOT could have done something, because up to then - nada.
