My disc brake lever almost touches the handlebar grip before the front brake actually works. The actual brakes are shimano 545 and the bike is new. Any help would be much appreciated.

    Look at the instructions I linked in my previous post and you will see how to adjust your brakes.

    cobba those instructions are for mechanical disc brakes and mine are hydraulic brakes.

    foy, can you take the bike back to the shop?

    possibly only need setting up, but may need a bleed. either way, the shop shouldn't have given it to you in that state.

    Yes you are right andrew but the only problem is that i got the bike from ireland by mail order so i am pretty stumped on that one. They never set the bike up proper as the gears are jumping and i had to tighten up the bottle cage bosses and rack mount bosses as well, how the hell it passed a pdi check beggars belief!

    my friend had this happen to his new carrera the other day on the leaver you should have a allen key adjustment to move the leaver closer or further away from the bars will be a small one and it will be between the lever and where you put the fluid should just be a case of adjusting this out

    You mustn't have the 545 then.

    sorry cobba i got it wrong the brakes were 575 not 545 as i said. i have got it sorted now after some great advice from fingz 999, i just cannot believe how simple it was in the end.
