[Resolved] [Technical] 'Soft' front brakes

[His Dudeness]

Cable tie the lever closed overnight. It can force the air back up to the master cylinder. Do it a few nights in a row

[unfazed]

If the problem was not there before you changed the fitting then it is most likely air.

I presume you are bleeding them correctly.
Pump the lever, hold it, release the nipple, keeping pressure on the lever. do up the nipple, release the lever. Restart pumping the lever again.

If tying up the lever like His Dudeness says does not work try bleed the lines from the master cylinder down by loosening the banjo bolt like the bleed nipples.
If no success, remove the calipers one side at the time and push the pistons back fully, use a clamp or something to hold them in the fully pushed back position. Now bleed them again, you will need a helper to pump the lever, while you open and close the bleed nipple.

Sometime air can get trapped around banjo or in the calipers and this normally resolves it.

They've had a standard bleed at the garage which improved the feel, but i might well whip the callipers off and do as advised.

So; I cleaned my callipers/pads/pistons today.

Rear was all good, but the front right had one piston pop out, now my brakes are worse, and there still might be air trapped in the bridging line over the mudguard. Also discovered a leak on the double set of banjos on the right side.

Brakes work, but wouldn't like to have to use them in an emergency.

Back down to the garage in the morning for a proper look, new washers and some investigation.

Why are you bridging across the mudguard?  :eek The best method for the fazer is 2 lines from the master cylinder, one to each caliper.

Because that's how it was done. May end up the other way, though. See how it goes tomorrow.

Is there any specific reason that it's the best method?

[unfazed]

Equal pressure to both calipers immediately.

[richfzs]

Easier to bleed as well. Less joints to make / fail.

[helloindustries]

I can see the equal pressure theory working, but there are exactly the same number of joints with either method.

Anyway: Fixed now.
Turns out that the washers on the right side were in need of replacing.
