Re: Bleeding Brakes (front)
1. Cap off the brake fluid reservoir. After removal of the old pads the front pistons just need to be pushed gently in a bit to allow new pads over disk - not wound in like the rears. I've never 'overflowed' the reservoir like this but maybe worth taking a little fluid out if you wish.
2.N/A
3. Yes - buy pads for your car with the 'warning' electric plugs on. GSF will know what you need from your reg' no. Remove any foil from the pads before fitting. Some are directional - fit the right pads to the right side!
4. As long as you know what you're doing then it is a DIY job.
Re: Bleeding Brakes (front)
It certainly an easy job if you push the the brake fluid back...This is not recommended as you can push dirty fluid into the ABS pump causing it to fail.
I personally clamp the flexy hose and push the fliud out through he bleed screw. still no need to bleed and allot better for the system.
