Hi guys
Just a quick one.
I was in a traffic jam today and i was doing alot of stopping and starting.
I noticed that when i pumped the brake pedal it went rock solid and the brakes wouldn't work.
But if i gave the engine a rev the pedal would go soft and the brakes would work again.
Now this is extremely scary and i would love it if anyone could help me out as i have no idea what is going on.
