Okay, so I was changing my brake pads, for some nice fancy Galfer premium ones..

I managed to get them out okay... but then I couldn't for the LIFE of me get the new ones in.
So I phone bikerboy and he suggested I remove the calliper from the forks.

That was were the first problem occurred. Eventually, I managed to get the stuck bolts loose, and free the calliper from the forks and remove it.

Now, the reason I couldn't get the new pads in of course was because I needed to push the pistons back to make space. No joy, they simply refused to budge. Eventually... out came the mallet.

Now, the mallet was working great, I was slowly pushing one of the pistons back in place, when suddenly I am covered in brake fluid!! The other piston had come FLYING out of the calliper, dumping it's entire contents of brake fluid in a rather projectile fashion.

So I managed to push that piston back in to the calliper, and figured out how to reattach the little clip that came off.
Luckily the pistons were now flush with the calliper and I was able to get the new pads in, and back on the bike.

NOW, my problem was bleeding the system, because of all the fluid that was lost and replaced with air.
A LONG time later, my brakes started biting!! So I kept bleeding until no more air would come out...

I took the bike for a quick spin around the block,and the good news is that it stops. Eventually.
Rather, the brakes have plenty of stopping power, it just feels....

It feels like I am stopping my bike with a pillow. REALLY soft and spongy. BUT, it is a very STICKY pillow, because it does actually have a lot of stopping power, even if the brakes give no resistance themselves. It is a really weird senstation.

I shall be going to the garage in the morning I think to get them checked over...

No it's new pads on old discs, give them time to bed in, once they are, all will feel normal again. When you bleed the front, if you take the reservoir lid off and leave it off, squeeze the lever gently and bubbles should be seen. Keep an eye on the level. Leave the lever overnight with a zip tie holding the lever on, then bleed the next day, this should get all the air bubbles to one place, and bingo, super responsive braking, but most of the feel will be pads bedding in.

Please do not beat pistons with a mallet, g-clamp at worst and slowly sqeeze the pistons back in carefully and parallel, prevents damaging seals.
