Brake Fluid amount for complete flush

Postby fnickel » Wed Feb 06, 2013 6:11 am



Just wondering how much brake fluid to buy to flush out all the brake lines and clutch lines and refill complete systems on a '92 1500SE. Sorry if this has been previously answered.

There is no refrence to the ounce amount in owner or shop manuals. Bought a quart bottle and had more than half left over.

I just bled my two bikes, GL1500 and BMW F650. 12 FL. OZ covered all the brakes and GL's clutch and had left over.

A bleed is different than a flush...
A flush is trying to get ALL the old fluid to be replaced with NEW fluid.
A bleed is just pulling enough through the system to remove air and small particulates of contaminated fluid...
I do not have the answer ..but when I do mine I buy a few bottles and take back the unopened ones when I am done..
It's cheap enough anyway to have an unopened can laying around...
Be sure to suck out the old from the resevoir and refresh before sucking the fluid through the lines and calipers.
That snow like stuff in the calipers will grow as it ages and reduces your braking power so a complete flush every 2 years (or 12K miles according to Wing World magazine this month) is an absolute must.
I do mine every year - but I average 12K + every year too....

according to Wingsconsin's definition, I "flushed" my two bikes, GL1500 (breaks & clutch) and BMW F650 (brakes) with 12 FL. OZ brake fluid and had left over.

If you are trying to do a flush, it is also a good idea to push each brake piston in the caliper back fully otherwise a lot of the brake fluid in the caliper does not get changed when you just pump fluid through the brake system and out the bleed nipple.

1 456ml/pint bottle of DOT 4 Brake fluid will be just enough to do a complete flush of your brake/clutch systems.

Do not keep opened containers as it will attract water, and weaken its capabilities when put to use. Another reason to change the fluid every two years (the same for cars).

The world is not going to finish today, as it is already tomorrow in Australia and New Zealand, and other islands of foreign nations such as Guam and Samoa.
