Draining brake fluid

Bludge · Post by **Bludge** » Mon Sep 23, 2013 3:06 pm

Im going to be removing the braking system from my scrapper this week, calipers, braided hoses, master cylinder and servo.
I was thinking of removing the fluid from the master, then pumping the remaining fluid through the caliper bleed nipples by pumping the brake.

Will this be ok, or is it likely to damage seals etc?

You don't want to be pumping it without any fluid in.

Remove the master cylinder cover, remove a brake line from a caliper, and just let it drain out naturally.

Suck out the fluid from the master cylinder then just undo the brake lines at the calipers, all the remaining fluid should flow out if the master cylinder cap is off.

Great minds, @Confused

Ah cool, i wasnt sure if all the fluid would drain without some sort of force. thanks guys.

You're right, it won't - the force it needs? Gravity!

Alright smartarse!

i wasnt sure if any fluid would be left in the lines where they run parallel to the ground that would drain out when the car is moved.

I'm sure it will be fine, any residue will be minimal.. you could always empty it, fill it, flush it and refill it again, just to be sure - but I think that's going a little too far personally.

Yeah im sure it will be, but i dont want all sorts of fluids covering the guys truck when he comes to take it away! lol.

haha fair play. You could put the brake lines back on the calipers after draining if you're worried, or crimp the ends over with a cable tie/tape etc..
