Changing caliper, how do I stop the fluid from leaking out of the brake line?

[addnon]

as the title states...bit confused here. once I disconnect the line, won't all the fluid drip out and drain the master cylinder? it looks like its too hard to clamp or ziptie... can I plug it?

[twastheglow]

Yes, it will start dripping. Just have the other caliper there and hook the line up to the new one then top off the MC as needed.

of course it'll leak you are changing the caliper...? you have to bleed the brakes after anyway which will require a brake bleeding kit (buy at any local auto supply store). I would suggest going onto the DIY site or looking up how to bleed brakes so you don't screw yourself

hahaha Yeah, I forgot to mention that part. lol

Using a stick or pole to hold the brake pedal down will help control the amount of fluid that leaks out.

Or you can save the money and use the ancient two person method...which believe it or not...works too.

^still need to buy the adapter that will fit in the bleed hole otherwise you get can get air in the hose, even if you are using the two person method, or at least a hose that can fit around it.

Never had this issue and I've done it multiple times on three different E36s.

[lilbouk]

plus with the two person method you get an awesome leg workout!!!!

so you don't even use a hose? just led it bleed onto itself? I'm confused? I've always bled with a bud and I spent the extra $10 for a tube, a cup, and a plastic adapter that fit into the bleed hole.

Nothing to be confused about. I've never used a hose, period. Not one issue to this day.

^ too much clean up bleeding them onto themselves, no thanks

As long as you don't remove the old caliper, hit the sack, and then replace with a new on in the morning, it'll be fine. The amount that drips out, assuming you get the new caliper on within a few minutes, is negligible.

Also, if you have had the brake lines loosened in the recent future (as in, they aren't still torqued from the factory), I'd also recommend removing the brake line with the caliper, vs. having to spin off the caliper. I had trouble threading the new caliper onto the line as you literally have to spin the whole damn thing. It was much easier to just remove the line (the fixed hard line is what has the hardware that spins. . .the flex line just comes off at the union).

[Stuntman]

You can always use a plastic bag and zip tie the line as high as possible. It will still drip but not as bad and won't make a mess. Just re-bleed and you'll be good to go.

Bleeding: Use 2 people.

Pump brake pedal ~6 times
Press pedal to floor
Open caliper nipple to bleed the fluid.
Close caliper nipple
Release brake pedal

(repeat at Pump ~6 times).

Go to your local autoparts store. Get some vacuum caps, which are used to cap off small vacuum ports on the motor. Remove line from caliper, plug line with vacuum cap. Nothing leaks.

They make them in all kinds of different sizes, they're cheap, and work very well.

this metal plug is not what he is looking for, that is designed to plug and seal a brake line fitting that uses an M12X1.0 thread with a Double type flare.
