Hello sorry if this was already posted but i could not find it.
I am trying to pinch my brake line to see if my master cylinder or brake cylinders are leaking.
BUT the line seems to be hard to pinch off.. can the lines on my bike be pinched off or is there a flexable solid tubing inside that i will damage? Ps i am trying to pinch the flexable line not the obvious solid lines.

My brakes are loosing pressure i have to pump the lever to get any pressure then it goes away.
This condition is most likely caused by worn/leaking cup seals and/or corrosion damage in the bore of the master cylinder. To fix it you can either replace the master cylinder with OEM, or repair your master cylinder with a high quality rebuild kit. You won't know whether your MC is rebuildable or not until you disassemble it to check for heavy pitting/corrosion in the bore.
