Yes.
Pretty sure that cover is a dust cap, you’re maybe leaking oil through the piston seals?
try pushing the pistons in with a plastic lever. then bleed with a bleeding block
Piston looks overextended and might be damaged.
Did you unscrew the silver torx bolt by any chance?
You’ve cracked the pistons, it’s toast, lucky it’s not expensive and now you get to learn the added bonus of putting barbs and olives on! Next time just bleed in situ on the bike and then use brake cleaner liberally
I guess the Quad-Rings inside the brake callipers are leaking.
I highly recommend to replace the whole brake calliper.
They are cheap. Take no risk here …
Leaky seal means, for most of us, replace the entire caliper. Hard to find parts. Hard to repair even if you find parts.
Thanks all! I will replace the caliper if i can find or buy a second hand rear brake set to just plug and go
Wait, did you try to use some cardboard as a bleeding block? If so, then just push the piston back into place and repeat the bleeding with a normal plastic bleeding block
Gnarly break pads dude
I would buy a new caliper this one has been messed with pretty bad. Mismatched screws holding the case together and such you may have other problems fatrher in from that piston being skewed and this caliper is not extremely expensive
you might need a new caliper
if you can replace the SEALS do that…. no need for a new PISTONS if its not damaged…. as fkr replacing the seals theres alot of tutorials on youtube… but if youre unsure how, go to reputable BIKESHOP then have it done…. seals are cheap… you can see buy them thru shopee and lazada
i know this coz ive been there…. done that,
