Front brake!
exvalvesetdabbler:
I have to agree with honda-san, that build up of not only muck but corrosion behind the seal. Also as the seal ages it becomes hard it's less likely to pull the piston back. Also if you have changed the fixed pad you might need to reset the clearance to the disk to 0.15mm. Just slacken off the adjuster for the fixed pad and slip in a feeler gage and then tighten up the adjuster until it starts to grip the feeler gage then back it off a little.
Best of luck.

Right chaps- I stripped and cleaned the caliper- it was clean(ish)- Ive had worse! I removed the seal and cleaned groove out with cotton-bud- washer the whole lot in hot water and fairy- blew it all dry with compressor- Now it is all back together you can see the caliper moving and no drag. But- I fited the old pads- as I think the problem is pitting on the piston causing stiction. I will re-set one the inner pad (which is new) beds in properly- as its only doing about 20% of its work judging by the marking on it. Theres just no way I can think of to bed thse pads in so they give 100% contact of the disc. So, off the the MOT place agin this week. The jobs a whole lot easier when you can legally run the bike on the road and do these tweeks!

Hi Folks,
Interesting reading on the recon of a 400/4 front brake. I did mine, followed both of the manuals, advice from sites like this, used all the right components mostly new or cleaned like a new pin, Used the right grease in the right places................. Brake works a treat, BUT........ it squeels like a good en when applied, something it never did before......... any ideas please ???
COLIN.

I found using genuine Honda brake pads resolved the squeal problem. Twice the price of pattern ones of course but the front brake seems a whole lot better now. The brake hoses are the standard ones and I'm using silicone fluid. I know there is some questions as to the suitability of using silicone fluid in these old bikes in that in can have an adverse effect on the seals. I've been using it for at least five years now with no probems.
