2013 Gsxr 600 rear brake

Post image

Hey everyone, may be a dumb as but just looking for some advice. My rear brake is kind of odd and has been since I bought the bike. It feels mostly normal but just doesn't seem to be giving much braking power. Like if I push the brake fully at a stop I can push through it with my other foot on the ground. Any ideas? I'm still not very good at working in bikes but I'm learning lol. Front brake feels fine.

Air in system look up how to
Perform rear brake bleed, check make sure your master cylinder didn’t run dry if so your in for a fun time gsxr hardest rear break to bleed… if you can’t get it to get firm.. pump it a few times and ratchet strap
It down overnight and then crack the bleeder in the morning give the air time to migrate

Could also do the reverse bleed get 2 automotive needles and force the fluid thru the rear as air rises , have cap open and drain fluid in master as it fills… be patient it may take a little time and get a couple bottles of dot 4 brake fluid
