It has been a while since I posted on here.
I started my car on Monday, drove it and all was good. I parked it up for 7 hours and when I went to drive it again (while approaching a roundabout) I realised I had NO BRAKES! The pedal was hard but useless (no jokes please), almost like how they are when you don't have the car running and you apply them lots. After about 3 minutes and 4 roundabouts of shitting myself, they worked perfectly.
The exact same thing happened again yesterday, fine in the morning, deathtrap at night-though I left the engine running for 5 minutes to defrost the car in the morning.
Can anyone give me any ideas why this is happening-before something very bad happens!
Much appreciated.
