bleeding brakes

[david taylor]

I would like to bleed the brakes on my 2000 alpine, like old times pump, and hold, I here noise when pushing the brakes? I see two calipers with line going to the bottom one, and the bleeder on the top one. I bleed both of these?.noise is ok?. Do I need a bleeder vacuum to do the job?.

THANKS DAVID TAYLOR TAYLORS2U@q.com

I'm not too sure how to answer the question about noise but use the bleeder valve at the top to do the bleeding do not try to use the lines if that's the second part of your question.

Bleed the farthest cylinder from the master cylinder first which usually comes out to left rear first, right rear second, right front third and left front fourth.

The noise you hear is the electric backup pump operating, it comes on when there is no hydraulic pressure, i.e. no engine running. The bleed screw is at the top of the caliper but if you are doing this on your own you may want to install speed bleeders. Are you trying to get air out of the system or are you doing a complete flush and replacement with new fluid? If you do a search on bleeding brakes in this forum you will find endless discussions on the topic.
One minor correction to John's note is that the right rear is the furthest away from the master cylinder on the Alpine.

all these years I've been listening to the pump and I guess I just don't think about it anymore

Lots of "advice" on the forum to consider--does your 2000 have two- or four-piston calipers? If 4-piston, you can only reach the inside calipers w/out removing the wheels. TIP--go to autozone and get a hand vacuum pump[$25], first remove/replace fluid in reservoirs, then use pump to draw new fluid to/through calipers, replace fluid in reservoirs as you go.

IIRC I used about one and one half gallons of fluid. Had to send DW to the parts store........twice.
