Default Yamaha R15 1.0(2010) rear disc brake issue

Hi guyzz.. I m facing a strange issue with rear brake of my R15 rear disc brake.. It works perfectly fine when I start riding the bike but after 15-20 minutes of ride it suddenly stops functioning .. The brake paddle goes to the bottom if pressed... and again after 2-3 minutes of halt it comes back to normal...

showed the bike at the showroom(m.p motors , Pune) they say no issues with brake... please help me if you have any idea on this..

Thanks...

Tell them to check the whole rear brake assembly such as the rear brake cylinder, linings, calipers and the pads.
Check the oil level of the rear cylinder.
This maybe mainly due to leakage from the brake lines.
Or get it checked,serviced at a different service centre.

How many kms on the bike?
How many kms on the brake pad?

Do you ride with your right foot resting on the brake pedal?

Can't be sure but maybe the pistons have dirt stuck in them which isn't allowing them to retract fully.. So the brake pads are constantly pressing against the disk (they are in contact with the disk normally too but in this case they'll be exerting some force)

Eventually the pads overheat and fade out and won't function as required..

I had the same issue before.... and i don't have much knowledge about the bikes and i got help from many people...

Try to get the brake bleeded for once and check the brake oil level...

If you see it low then fill it up with DOT3 ... i use Motul Dot4

check the brake pad

If you have recently done Teflon coating then it is normal the service center person will also apply it on the disk and the pad slips from the disk.

In rare case there is screw on the rear end of the brake peddle that might be very loose or the threading might be gone.
you will get the screw for 30 RS it looks very good and is used to adjust the brake intensity check that.

i mainly thing is bleeding the brakes will fix it... because there might be air bubbles in the rear brake that is the reason...

I have very less knowledge about bikes and the above statements are the problem that i faced.....
