Brake set up AD/FS990 's

Afternoon all,

Wondering if anyone has a link to or can post some directions to setting up an FS990/AD990 so it grabs like it should, mine feels dull and hard to pull and just slurrs  ??

I recently took some Aluminium 48's off a bike i have and put some Tuff II's on it and i just can't get the brakes to grab like they should, got some on a Haro Sport and it locks solid on both aluminium and tuff rims and is a joy to ride but on this other bike its just, well... pants !  Like there is not enough movement and the movement it has is too slow and stiff (if that makes any sense?) I have fiddled (i'd like to say adjusted but it just doesnt cut it) with the spring retainers to get the pads evenly spaced etc but feel i've messed up the torque they should provide ?

I've searched the net and found very little, i searched the site and found very little also so just a few pointers to get me started would be a great help !

Undo the allen bolt, and put a spanner on the spring retainer. Whilst holding the allen key in the allen key bolt, do up the spring retainer with the spanner until you feel you have a good torque on the spring, then do up the allen key bolt to hold it there. Try and keep the torque the same on both sides (the spring retainer should be slotted to hold the spanner and try and get them in an equal position on both sides, like mirror image)

Thats the best starting point  :daumenhoch:

I'm such a dork, i didnt even think of just holding them with the spanner and pulling the lever to see if it was in the correct place LOFL i may be able to build cars and engineer hydraulic systems but a brake caliper... oooohh tricky stuff. :uglystupid2:

I will get on this tonight, thanks.
