My Raleigh Bike. The Start.

Have you tried the adjustment screw? Turn it one way and then the other and see what the effect. You may need a longer drop calliper.

Not yet but I will have a look now.

Here's one on ebay and the top one that has different lengths..

I have had similar when I started doing up bikes - have you put the QR lever in to the down position, released the cable and rotated the brake?
I can't see any reason why someone would try to put different drop brake callipers together - unless they like the smell of burning rubber

When pulled up in tension they would be fine.

@youngoldbloke .. Just been up there and had a look but I can't see an adjustment screw.

There are no cables in place yet but the front brake are ok..

Here's service instructions for similar callipers https://si.shimano.com/pdfs/si/SI-T-25A-000-00-ENG.pdf showing the centring adjustment screw. Link to Shimano tech docs here: https://si.shimano.com/#/

My heads bagging now so I will have another go tomorrow, but I will connect the brake cable up tomorrow and see if that makes any difference.

You've fitted the caliper 'On The Piss' misaligned

Those 105 callipers are short reach. I suggest that just by chance the front calliper happens to fit OK, but that your old frame requires a longer reach rear calliper. I don't think 105s came in a long reach (?). R450, 451, 650 maybe? 47 - 57mm drop

That's what I thought last night while watching pool on u tube. So I went on ebay and got some almost new Exage 47/57 calipers which will do the trick, so I will stick the others back on ebay tomorrow.
Still its all a learning curve for me so grateful for all your help.

If only it was that simple..

As most of the bike is stripped down how easy would it be to take the BB out and re grease and what tools would I need. The bloke at the bike shop said he would re grease the BB for a tenner?

That would get my vote all day long
