brake resovoir flexes when brakes are applied need help!!
 

ok my brakes were getting worn out and ive been doing some preventative maintenance on them. ive got new calipers and pads-ANYWAYS i went to BLEED them and i noticed as the brakes were pressed the lid on my brake fluid resoivoir was flexing with them! i bought a new seal for the cap also. SO WHAT does this mean???why would pressure be pushing back thru there? should i replace the master cylinder? thats what i was thinking but who knows? let mE KNOW WHAT YOU THINK AND IF YOU HAVE EXPIERIENCED THIS
:hmmm:

Is the cap trying to fly off the reservoir or are you just seeing the normal flexing of the whole master cylinder and brake booster assembly?

its not flying off no- but i was told it wasnt supposed to flex above the master cylinder. does this mean its time for a new master cylinder
?
