Generally speaking that sounds as per normal, maybe you have never tried pumping the pedal with the engine "off" then started it - if that is all it is then what you are experiencing is the servo doing its job, plus a bit of you needing to wait until the new pads have bedded in.Hi
Great "How to thread", but I have run into a problem!!
After completing the procedure as per instructions - I pumped the brake pedal but found that the pressure is dropping once the car is started?? It is fine when engine not started.
Is this a sign of needing to bleed the system or a master cylinder issue?
Just for the record - no bleed nipples cracked open and no brake fluid overflowed and the brake fluid level is fine??
