Brake problem

I changed the front discs and pads on my 300 TDI disco over the wkend. i split the calliper its self to get one of the discs on as the bottom calliper bolt was stuck solid. I no i shudnt of done it this way. Now my problem is that after iv put it all to gether bleed all four brakes, when i press the pedal there is a lot of travel. I have some new calliper seals on order, as I knackered one of the seals between the 2 half's of the calliper Do you this this will fix the problem or could it of done something to the master cylinder ? Thanks Andy

old master cylinders often knacker seals when pedal is pushed further than normal during bleeding ,but make sure caliper seals care perfect first

ok thanks fella ill try the seal first
