Customer isn't always right!

Customer - My brake needs bleeding! Me - why do you think it might need doing? Customer - the lever comes all the way back to the bars. Me - ok - does it pump up if you activate the levers a few times. Customer - no but it defo needs bleeding. I am now suspicious. Squeeze the lever and it feels like no pressure at all in the brake - feels like all the fluid has gone - but where to? Closer inspection reveals fluid around the lever pivot - not a good sign. It makes a squishing noice like air is being sucked back in on release. It is also impossible to push fluid through from caliper to lever or vice-versa - until hose is disconnected. Therefore it is the lever that has a problem. Strip lever and in doing so find everything wet with brake fluid- seals have disintegrated. Lever rebuild required. End of story :)
