Spent the day installing the front brakes and "trying" to bleed the rears.

The front brakes went together like a breeze. The rear, not so. Struggled to bleed the rears, finally pushed fluid back into the system from the caliper... this was going well, or so I thought, until the hose jumped off the tool and sprayed brake fluied EVERYWHERE!!!

OMG, what a mess.

Got that cleaned up, but peddle is STILL soft, shoot!!!

Put the project away for the night, pounded down a couple of beers, will figure this out later.

What did you use to clean those discs up with?

villageidiot · 02-16-2013, 10:35 PM

Tink,

Fill the rear reservoir, hook a line up to the bleeder, put line in bottle. Open bleeder.

Wait for fluid to run out of bleeder into line.

Then just pressure bleed as normal, 3 pumps, hold down, open bleeder, pedal down. Close bleeder.

Make sure you wipe up the fluid mess with clean water or your paint will hate you.

Thanx!

Let us know if you "feel" that surface when you start riding. I have some surface grunge I need to get off mine as well.

You won't notice a thing after hitting it with a disc. First couple stops it'll bed the pads in, then it's smooth braking.

Can use a scotch brite disc. Or the actually make a brake surface prep disc.

Thanx! I was thinking Scitchbrite, but will look into the surface prep disc.

The price of those rotors is staggering!

After trying to bleed the rear brakes using every method known to man, I determined the master is the problem, RATS!

Okay BMW brake expert, put on your thinking caps...

So here's the question; should the new piston, with the cup shaped seal, have holes in the front like the old piston?
I'm thinking my problem is that with the new piston (no holes) I'm not getting brake fluid flow from the master reservoir to the brake caliper when I release the brake piston and it returns to the starting position?

This is the old piston I took out, note the hole in the seal grove

This hole goes through to the front of the piston, there are two of them.

This is the old seal, note that it is not cup shaped but rather it is rounded like an o-ring...

And this is the new piston with a cup shaped seal and no holes under the front seal.
