Yes that is very true

I will bleed them on Thursday when I get some cash.
Just nearly rear ended a van coz of it.
Pulled up behind a van at a roundabout brakes worked fine was going forward car lengths at at time as cars pulled away infront. Went to brake as normal and nothing happens. Push a tiny bit harder and it locked up.
I have noticed for a wile that when I'm sat in trafic and I have my foot on brake pedal it goes down slowly under my foot in like steps. Goes down abit and stop then abit more and stops. Then I pump it and it es back up. Then slowly drops again with my foot on it.
Is that normal?
