Avid bb7 lipping
Posted: 9 May 2018, 7:28pm
Hi All,
While I am waiting for a replacement crank for my everyday bike I pulled out my touring bike which hasn't been used since last August, I had a knee injury just before a 500 mile tour through spain/france. It turns out the knee injury was a torn meniscus and it's taken this long to be fully functional... Only explaining so you don't think I have been lazy
So this evening I have been giving it a good service so I can use it in the meantime, did all the normal cleaning greasing and noticed the front brake was extremely poor (Avid BB7's - i gave the rotors a good clean and took the pads out to examine them, there was some use left in them but despite readjustment the braking was still fairly poor.
I examined the pads more closely and towards the bottom there was about 2mm of lip so I changed the pads for new ones readjusted the brakes and they are rock solid again.
My question then: Is this lipping normal not seen it before, there's no adverse wear on the rotors they are the ice ones from Shimano. The brakes were set up correctly on the old ones (you will have to take my word on that) , I might have expected lipping if the brakes weren't fitted right and somehow the pads stood proud of the rotors at the outer edge, but the lipping was on the lower edge facing towards the inner of the rotor.
The last cycle was from Santander through to france and there were some pretty steep hills and lots of gradient, I cycle camp so the bike is always heavy loaded kitchen sink etc.. and I am 6ft 1inch and weigh 18.5 stone so they have a lot of weight to stop... could this be the cause although ive not noticed that lipping previously?
Strange so wondered if anyone had any thoughts?
