Changng Brake fluid - Step by Step

[Lindenberg]

Can someone please enlighten me with the steps to follow to change out the brake fluid on my 2000 Alpine?

The Bosch manual states to bleed the break you...

1 Check the master cylinder reservoir and fill if necessary
with DOT 3 or DOT 4 brake fluid.
2 Bleed the entire brake system per vehicle manufacturer’s
service instructions.
3 Bleed the caliper assemblies in the following order.
Right rear
Left rear
Right front
Left front
4 Tighten bleed screw to 8-15 lb.-ft. (10-20 N•m).

Since I want to change out all the fluid I need to know the following.

Should I remove as much old brake fluid as possible from the master cylinder then fill with DOT 3 or SOT 4 brake fluid before I begin bleeding the brakes?

How much fluid should I let drain out of each brake caliper to know the old fluid has been replaced for the front and rear?

Tom,

Get rid of all of the old fluid in the master cylinder reservoir and replace with new. I would think that you could see when the fluid changed from old to new as it comes out when bleeding.

If your brake system is the same as 2002 your will find that there is 2 bleeders on each caliper. The outer bleeders can only be accessed by removing the wheels I found. Used 2 1/2 quarts of Dot 3. The rest of your information is correct.

Tom- good practice for a full bleed is to remove as much fluid as possible first, then fill to or near the top w/fresh. Then do the bleed in the order you state. If it has been a while since you last changed brake fluid, it should be obvious when the bleed is done. If you have fairly fresh fluid now, you wouldn't notice much color change, & you'll have to wing it. 2.5-3 quarts should do it. I've heard 4, but I think they were doing anti-freeze shots & beers at the same time.

Also good practice to do the pin-slide lube at same time IMO.
