Lewis-Trials Posted November 19, 2008 Report Share Posted November 19, 2008 Hi well ive got a specialized p1 08 and ive got the Avid BB5 on the front and back. The back one is working superb but the front has never been the same after i broke it and so i need to buy new cable. when i put the brake back on and the rotor was bent looking in where the rotor is ment to be straight on to the pads. I can see ives got a buckle in the rim and will be getting sorted very soon but does that mean when the front wheel buckles the rotor becomes buckled with the rim. And if so does that mean ill have to buy new rotor or am i best to just buy a Avid BB7 of ebay for the front. Quote Link to comment Share on other sites More sharing options...
Jake Beach Posted November 19, 2008 Report Share Posted November 19, 2008 I don't think so. When you buckle a wheel I think only the rim bends not the whole wheel. Not sure. Try straitening the rotor with an adjustable spanner. Quote Link to comment Share on other sites More sharing options...
Danny Metcalfe Posted November 19, 2008 Report Share Posted November 19, 2008 Try straitening the rotor with an adjustable spanner.Most mechanics will press it flat for you, Probably for nothing, Or the cost of a pint I got one to press mine, When I bashed my front disc off a rock(: Quote Link to comment Share on other sites More sharing options...

BlAdE Posted November 20, 2008 Report Share Posted November 20, 2008 BB7 is better Quote Link to comment Share on other sites More sharing options...
sstein Posted November 20, 2008 Report Share Posted November 20, 2008 You seem pretty insistent about the bb7, if you want one then buy it. So you know most discs that have been used have a slight bend in them, not usually a problem, but one off of ebay will probably be the same as yours, try just bending yours back or get your lbs to do it.

stoozie Posted November 20, 2008 Report Share Posted November 20, 2008 (edited) Alright thanks i was thinking of getting a Avid Bb7 for the front becuase there used by trials riders. or just buy a new rotor or whatPut some research into it before you go and buy something, instead of buying it because you'd heard "it's a good brake" or whatever else your buying.

davey1991 Posted November 21, 2008 Report Share Posted November 21, 2008 You don't need the whole new brake set-up, as people have said try get the disc straightened, buy a new cable if needs be but dont go for a new bb7. There just not as good as a well set up bb5 in my opinion, they seem to hold much better and still have modulation. Quote Link to comment Share on other sites More sharing options...
DrEvil270183 Posted November 21, 2008 Report Share Posted November 21, 2008 When a rim is buckle it does not effect the hub, therefore does not effect the rotor for the brake.Your bb 5 prob just needs setting up, new pads, cables, bit of lube in the outer cable and adjusting so it bites etc. Rotor always bend, as said above - use a small adjustable spanner to get it running correctly. chance are you won't get it straight but do your best to get it so it doesn't rub on the pads.The upgrade of bb5 to bb7 is mainly the dial adjustments on both sides of the brake caliper. BB7 has two, BB5 has one. Possible slightly different caliper body design but I;m sure as you already have the Bb5 you could get it set up to work as well. Save your money for other much needed parts, like stronger rims Tim Quote Link to comment Share on other sites More sharing options...
