rear hydraulic

[jacktheripper]

hi all

i have fitted a rear hydraulic on scoot and the pads lock onto disc and locks up back wheel, its a saigon scoot one, i hadproblem last year then changed caliper and it was fine, had new engine fitted so dismantled everything but kept hose etc in tact, scoot sat for 7 months and its happening again

Could be pistons seizing up through lack of use. I normally remove the pistons and polish all surfaces with fine metal polish. Don't forget NEW seals.
