I will have a look. Thanks everyone for all the tips.
A final question. If it turns out to be the one-way check valve which is gone. What is the spare no and what is it called for buying a new one? I can not find it on ebay.
If i am failing finding a new I will have a look in the local brakers yard
Hi All
I am the proud owner of a 03 plate T4 Hippo.
Last time I was out and enjoyed driving my dear Hippo I noticed something odd when I used the brakes.
By pumping the brake pedal it became harder and harder. As it pedal became harder to push the brakes became less effective.
Leaving the brakes...
