For somebody on a budget, is the BB5 a better deal?

I just bought an 08 Diamondback Response Sport. Nice bike, big fan of it. Comes with Hayes MX4 disc brakes, which seem to be an absolute bear to tune right. I'm hearing the MX4's are preeeeetty darn low end.

The one thing I've been hearing is the ease of tuning with the BB7, but for 45 a pop it's just kind of... ehh... but I found BB5's for 30 a pop... more in my league.

Is there a significant difference that would justify waiting to get BB7's? Or should I get the 5's and be happy?

Or, is there another disc brake option (decently priced, of course) that would be an upgrade from my MX4's that I should consider?

I'm pretty sure the BB5's only allow pad adjustment from one side; if so, you really want to go with BB7's. Also note that the '08 BB7 package includes some extra mounting adapters that you may have to buy separately with earlier-year packages (not sure if this is true for the 160mm rotor, but it was for the 180mm front rotor package I bought).

I also have MX4's on another bike (as OEM equipment), and haven't had any major adjustment problems with them, even when swapping front wheels.

I'd say if you're going to change mechanical brakes, the BB7 would be a step up, the BB5 a step sideways.

BB7's are oh so nice. Very much recommended.

The BB-7 and the BB-5 are the same brake except the BB-7 can be adjusted from both sides for centering and the BB-5 can only be adjusted from one side.
I have BB-5's on my FSR-XC Comp. I've replaced the fork twice (I like to upgrade my forks) and had to completely re-align the BB-5 both times. I don't know what all the fuss is about. Yes it takes a few minutes longer to adjust the BB-5 compared to the BB-7 and yes if you've got the $$ go for the BB-7. But if you're on a budget, go for the BB-5s, I just purchased a set for my Rockhopper.
As for performance, the BB-5s are all the brake I need, excellent modulation, great braking power, the only brake I would upgrade to is a Avid hydraulic brake, but honestly, I don't think I need them.

The big fuss I'm having I think is more in relation to my rotors. The rear one is pretty bent. I think I got it straightened out, though... but while I was at it I was considering on upgrading due to the fact you get rotors with the package if I were to get bb7's.

I think I'll stick with what I got... good to hear the differences in bb5 and bb7. If I ever upgrade, it'll be bb7. We'll see what happens.

No, they're not. The caliper is different, the pads are different, the adjustments are different. The only thing in common is the Avid brand and the cps washers. They perform quite differently, too.
