Title: Front brake - Annual overhaul
Post by: cooleronthecoast on April 10, 2020, 02:35:45 PM
Moving the bike round in the garage recently I noticed the front brake was binding.  I removed the pin on the pivot arm a couple of months ago so I knew it was unlikely to be an issue with that, so I stripped down the calliper this morning and sure enough the piston was seized, so a quick rub over with some fine emery on the pad periphery and a clean up of the piston itself and all is well again.  Probably not this year (especially if we don't get out at all due to COVID19! )but next winter,  I'll be needing some new pads for the old girl.   Your opinions on what replacements to fit would be very welcome as the front brake does seem pretty rubbish especially when I've just got off one of my more modern bikes.  I've tended to buy EBC in the past, but if there's better material to use I'm all ears.

Try EBC sintered.

I couldn't get the ordinary EBC to work well.

But. Try replacing the caliper seal.


The old one could have hardened. And not retracted the piston

I'm normally happy with SBS pads but in the 550 they seem non existant. Far worse then my 750.
Maybe I need to overhaul everything  :-\

They ARE rubbish compared to modern bikes but then try a 1970 Triumph 650 and stop complaining!!

I'm not complaining it just suprises me everytime I ride it  it doesn't stop as well as the 750

Its true Bryan, the opposite problem is when you get on the Tuono after riding the 550, the brakes are that bloody good I nearly go over the handlebars the first time I pull the front brake on!

I did have a look at the seal John and it looked OK, but if I get further issues that will be something to check again.  I might just change the seal anyway when I get around to changing the brake pads
