2008 Focus 2.0 TDCI — Hard Brake

Recommended Posts

Hi - in the morning when starting my car... the break peddle takes about 15-plus seconds to go soft... sometimes longer. There’s brake fluid in the reservoir, no leaks by the peddle (that I can see). 

Can someone help me trouble shoot this please?

 

Kind regards

sounds like it's hard because the servo isn't doing it's job. Going back many years  I am pretty sure there was a ford service bulletin about that kind of problem on the Mk1 Focus and there was a modification that Ford dealers were told to do only if owners complained of this happening, it only happened when first starting engine. 

Is yours petrol or diesel.  My understanding is (unless my knowledge has gone out of date) that petrol engines just have a vaccuum pipe straight from inlet manifold to servo.

 Diesel has a vaccuum pump as the inlet vaccuum on the diesel engine is not enough. (might apply also apply petrol turbo models?)

Hi — thanks for replying. It’s a MK2 Diesel.

So I need to replace a vacuum pump?

Well I suppose it could be the servo or the pipe or the vacuum pump. Check for vaccum leak first along whole length of pipe and the end joints. Hopefully someone who knows these cars can guide you more. Which size engine? I do not know if the vacuum pumps are different on 1.6/1.8/ 2 litre
