Time for a brake.

Well its time to replace my rotors and pads but im not sure what works best with Juicy fives in xc mostly dry conditions.
it currently has the stock rotors and they never did work that well and always made noise so i would like to go with some other brand, i just dont know much at all about brakes.
i was thinking of also upgrading the size of the rotors while im at it as the stock ones are only 160mm and have no range. its either slightly grabbing or locking up, very little in between.

what type and size should i go with?

hope you can help me out , im looking to order them withing the next week or so.


forgot to add, they need to be 6 bolt pattern

I replaced my stock worn rotors with shimano slx rotors. Made a huge difference to the stock rotors I had. I just use tektro novela mech brakes but the difference was very noticeable compared to the tektro discs, even when new.

this can only be a problem with either your modulation, or the brake cylinder and lever.

larger rotors will give you more stopping power and more fade resistance. (the latter may not be an issue unless you do sustained descents.)


what's your budget?

well i was thinking somewhere around 100$ for a brake rebuild.

2x rotors at 30 ea
new caliper adapters to accommodate bigger disks at like 10 ea

new pads all around

and bleed them to be sure it all takes.

im sure its in need of a bleed by now, every now and then the lever goes dead signifying broken down fluid or an air pocket.
and on that note should i replace brake hose aswell? could be a pinhole somewhere causeing that issue.

everywhere ive read bigger rotors help the range as where it would drag without slowing you down now has some pull because of the extra leverage.
but granted any part of my brakes snafu could be the warped rotors . worn pads and need of a bleed.

anyways from what ive read those few rotors in my last post look pretty decent, im leaning twards the a1s as mrbr had a pretty good review on them ( as did the sls ) but the a1s come in red trim which is sort of where im going with my bike so the little extra touch ontop of performance would be nice for that same price tag.

Ok Bigger rotors are used up front to fight brake fade, mostly for down hill riders. Any normal/Non-pro rider should be fine with what ever size rotors come with any given bike. Adding bigger rotors adds weight.. I doubt you need bigger.

Warped bike rotors are easily straightened with a small crescent wrench. turn the bike upside down, hand turn the wheel and eyeball the rotor.
carefully bend it as needed as you see it hit one pad or the other. Bend a little at a time.. you can make any UN DAMAGED rotor perfectly straight in about 10 minutes..

Warn pads, again are you a down hiller ? or a regular hot shoe.... stock should be fine...

Bleeding,,If the system leaks fix em or has several years on it up north flush it..

I ride pretty fast I think, have had Inexpensive wet brakes and Mid level wet brakes, I never need more, always able to stop with one finger...

Is your cockpit set up correctly ??

ok ill give it a try but ive hated this avid crap rotor from day one , and the pads arent just warn they are glazed and squeel like mad.
but as far as size goes i do xc so i guess i dont need much bigger , only real fast downhills are small blasts in the woods but my current set up ( again could be the fact it need a bleed and pads ) isint enough to confidently brake into the corners.

if i can straighten them out a bit i may hold off for now on new ones but i do want to get a better setup.
