majorly need help!

[Guest LiamX11]

Hey guys need some advice badly. Hopped on the bike this morning and started riding but to my horror no front brake what so ever. The lever goes completely in with no resistance yet resivoir is full. There is a weird pulseing sensation in the lever if you hold it in. Back break works fine. So confused.

Souds like front master cylinder problem, first option price up a seal kit, then some one to fit it if your not comfortable doing it yourself.

Probably nearest to you Liam ?

Master cylinder was checked over on the weekend by uncle/mechanic. All seems ok. Brakes bled again aswell yet lever doesn't apply brakes till half way pulled in (which is an improvement) front brakes still pulses and discs make a horrible scrapeing/scratching noise. So checked pads which aren't old at all and plenty of life there and no foreign objects either. So more puzzled. But did notice when back brake is applied now it applys front brake alot stronger than it ever has before. Wondering if it could be me messing the combined system when bleeding?

They are a cow to bleed without a pressure bleeder. Well, a cow with one too...

Put a small drop of very light machine oil on each of the bobbins on each brake disk, the round circle bits that let the disk float. Obviously, don't go mad and get oil on the disk surface or pads!

Those bobbins might be stuck like Eddy says.

At the same time, if the discs dont rotate straight, they are "wobbling" and pushing brake pads away from them.

That causes many times soft feeling because you have to pump the brake so that the pads get closer again.

Fixed one Yam MT-01 that owner brought for brake problem, it had bad bearings and it caused that "pushing back" symptom.

There was no fault on the brakes, ok, pads was worn out because of that.

True is that our brake system is pain to bleed

Have you checked your disks for runnout , one could be warped ?

[Guest LiamX11]

Put oil on the bobbins/bearings weird pulseing sensations gone. Worked a treat. Just gotta try bleeding the beast again. Thanks for the help guys really appreciate it.
