Need advice - MTB Brake Pads

[Brakkies Sport Fotos]

I change the pads on the MTB. Hayes9 disk.

 

 

 

Took the wheels off, push a screwdriver between the old pads to open the gap, and put the new ones in.

 

 

 

When I put the wheel back, its not rolling free, (without ressistance)

 

 

 

How do I fix it?

 

 

 

Do I loosen the whole brake system and RE-Align it around the rotor?

 

 

 

or what

 

 

 

Any suggestions ?

 

 

 

thanks

Eish, pop-oog.  If the screwdriver thing doesn't work (thank goodness mine did!!) you'll have to open the reservoir containing the brake fluid and then try to push bake the calipers.

Were the hell is the reservoit. I'm technically challenged.

Dit sit bo-op die briekhandvatsel.... oppas net vir lug in die stelsel anners moet jy weer bloei!!!!! Oppas vir die skoefdraaier dit kan die Disk buig!!!!!

Popeye, yes, before doing ANYTHING with a screwdriver, remove the disks.  Then only try to push the calipers back after opening the reservoir.  See if you can't find the procedure for the Shimano brakes, that should help

I heard (but don't know anything about hydraulics) that youshould not use screwdrivers. Rather use tyre levers.

thx G*d for V-Brakes suckers ha ha ha

Ok stay away from the Shimano manual , I understand you got Hayes  . YOu should be able to push back the calipers without doing anyting funny , amd like Mampara said "not with a metal object" . If you gotta use the screwdriver then re-insert your old pads and then push back with screwdrivers on the old pads . With new pads and wheel  (but loose) inplace pull the brake lever and then tighten the wheel . (push the the lever towards the shock ) . You should be ok now .

Yes, got hayes, and reservior is NOT on the brakes (Oom H :-)

 

 

 

I did the screwdriver thing between the OLD pads (so they can suffer, I'm going to chuck them away)

 

 

 

Maybe: "pull the brake lever and then tighten" is the magic. Will give it a go.

 

 

 

Marius, Sorry, Why didn't you tell me before I baught disc brake that its a crap option? Nou's jy slimjan.. If I only knew.......

Marius, did your SC Superlight come standard with the V-bosses on the rear triangle or did you specially order them ?

Marius is still in the dark ages and a very mis-informed young man . One day you will pass him where he is lying in the bush cause his pads failed to stop his cause the mud got to much !! And just wait for the day his V's get outta alignment and he starts turning those little screws on the sides .

tHE Thug, I had to look hard to find a DS Frame of quality with V-Brake hangers. So SC was my first and best option, 2007 models don't have V-Brake hangers so I had to get the 2006 Frame.

Dirt Boy, I got ther XTR V-Brakes, the days of fiddling with V's are over, these babies stay true.

Popeye, Hayes Disks are designed to be self-aligning. You may find that taking the wheels off and putting new pads in has changed the alignment between the caliper and the rotor. Try loosening the two hex-bolts holding the caliper to the frame, spin the wheel and then slowly apply brake pressure, this will align the caliper and the rotor. Release the brake and tighten the bolts (carefully, so as not to shift their position), u may need to do this a few times to fine tune the brakes.

You can also visually check the alignment by looking through the gap in the caliper where you can see the rotor. Spin the wheel and check if the rotor is touching one side (left or right) of the pads, this can be fixed by following procedure above. If the rotor is touching both pads, the pads haven't opened enough (you may have accidently squeezed the brakes when the wheel was out), you either need to force them open further (there should be a plastic spacer that came with the brakes/bike) or bleed the brakes.

Hope this helps, I've had so much S*$## from my Hayes 9's, I've had to become a bit of an expert... next time definitely going for something like Avid Juicy's!
