brake disc

As my front tyre kept losing pressure I decided to have the inside of the wheel polished as it was porous, with the wheel off I noticed that the disc had a small crack in it. Damn and blast! Therefore a new one was on the cards so ordered one, it duly arrived two weeks later so could begin changing it.

As the bike is nearly 20 years old had to heat the disc to remove bolts a real struggle but new one fitted along with new pads and braided hose, hope to feel the benefit of it once pads bedded in.

Cost.
Disc £110
Pads £18 
Hose £32
 
Disc is something I would imagine not many people check so might be worth having a look.

Nice one Rick, I've never had a disc crack on the CB but it did happen on a mates Daytona.
Easiest way to get the bolts out is with an impact driver.

I'm not surprised you had to heat them up; they are usually pretty reluctant to move!

The new hoses should reduce some of the sponginess.

Never had a disc crack on a bike but bought a really dodgy Peugeot 306 once. Along a list of too many faults to list (it is a french car of course!) the front brake disc was cracked almost all of the way through. Fixed many faults and it still failed the MOT. Now languishing in a scapyard as that was all it was worth.

before doubting a porous interior, I suggest looking at the date of manufacture tire.
By experience idem
