Disc break questions

I'm currently running hayes mechanical breaks but I have a buddy who busted up his bike and is willing to sell me the hydrolic breaks from his bike for 50 bucks I'm wondering because I was interested in maybe getting 8 inch discs (I have 6" discs right now) so I'm wondering can you get different mounting hardware so you can still use the same disc break callipers on a larger disc or do you have to buy new calipers.

It depends on the model. Some OEM breaks can only be used on 6 inch rotors, some can be used with an adaptor to fit an 8 inch rotor. Check the manual or look it up online.

What kind of riding are you doing? Unless it's DH, there really isn't a need for an 8 inch rotor.

Yes we need to know what model hydraullic brakes they are...some will be able to fit an adapter for an 8" rotor.

I disagree. Especially when you factor in weight. 160mm rotors typically aren't powerful enough for a 200+lb. person in any form of biking.

It comes down to personal preference with the rotor size...however it also comes down to 'looks'. That said if he wants an 8" disc...go for it (if he can) .

I'm sorry, I completely forgot about that aspect. I do agree.

No problem. Just my experience as a 195lb rider. Wish I was lighter for the sake of not having to upgrade. Glad I'm not though cause I love upgrading. What a paradox.
