Do you unscrew the res cap (not all the way) when pushing the pistons back in to the calipers (Front pad replacement) to avoid having to bleed the brakes!?
 
I never have, afaik you do not need to bleed anything as long as you dont disconnect the pistons from the hoses.
 
Depends how far the piston has come out.

On a Micra I did a few months back the pads were so low pushing the pistons back in caused the resivoir to overflow (where it had been topped up previously too)!

Jez is correct, no bleeding required. Although it only takes 15mins to do all 4 wheels so maybe worth it if it's never been done.
 
Thats what I thought!

I was totally confused today though!

Replaced the front pads on a MK4 GT TDi and wound the pistons back in slowly. Tested the pedal and it went all the way to the floor! :confused:
 
Yeah, basically just undo the cap off the resevoir, squeeze in the pistons with a g clamp , fit your pads and disks and away you go, u can get away with it but really if fluid is going into the resevoir then you build up pressure, i guess its just easier not to have that pressure.
Ignition off, all the ignition does is make a vacuum in your servo making the brake assisted, you dont need brake assistance for changing pads:P
 
Thanks guys, I just though i was going totally bonkers!

The pedal had no feel in it even after pumping for ages! it was spongy, usually i religiously unscrew the cap a few turns just in case, but obvioulsy not religiously enough!

Sorted now though, gave them a quick bleed and they were fine.

Grr. My garage is too cold and has too much junk it to fit the car in :(

Infact, I am clearing it out tomorrow. FUN!

Glad you sorted the brakes out. Maybe dont drive like a nutter to begin with incase something is amiss. Also, post your car up in the www.couk-motors.co.uk gallery.
