Sangsta. Posted March 15, 2011 Report Share Posted March 15, 2011 Hey all I started riding about 3 years ago i was trialling for about 1 year then due to injury i stopped but anyway i have HS33 brakes on my ONZA T-REX that where on it when i got it (it was a display model as well) well now i can pull in the brake and the brakes hit but i can also bring in the lever after that it the only hydraulic brake I've used so does it need to be bleed? any info?

trials owns Posted March 15, 2011 Report Share Posted March 15, 2011 yeah sounds like it needs a rebleed, check for any leaks before. Quote Link to comment Share on other sites More sharing options...

Sangsta. Posted March 16, 2011 Author Report Share Posted March 16, 2011 thanks for that link i do not think i have a leak due to the not changing in quality over it life time but i was wondering just how the brake should feel? should the lever be really stiff from when the pads hit the rim or is there always some give FYI i can pull it in about 1.5 cm after the pads touch sorry if i wasn't clear enough before thanks SangSta.

xXteh dirtjumper 54Xx Posted March 19, 2011 Report Share Posted March 19, 2011 hi, You should use two syringes, one and the master cylinder and one at the caliper. Guessing also you need to use dot 5 brake oil. Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted March 19, 2011 Report Share Posted March 19, 2011 I think what he's refering to is the extra 1.5mm travel is the frame flexing after the pads have hit the rim Quote Link to comment Share on other sites More sharing options...
xXteh dirtjumper 54Xx Posted March 19, 2011 Report Share Posted March 19, 2011 what about a Brake booster, have a look on tarty they have a 2 bolt echo booster for £25.53, LOOKS NICE ACTUALLY IN SILVER. Quote Link to comment Share on other sites More sharing options...
bing Posted March 20, 2011 Report Share Posted March 20, 2011 hi, You should use two syringes, one and the master cylinder and one at the caliper. Guessing also you need to use dot 5 brake oil. it`s not dot 5 brake fluid, its mineral oil you need, either magura royal blood or lhm mineral oil that is used in citreon car suspension. you can get the lhm stuff from halfords ands its cheaper per litre than royal blood. don`t use dot 5 it will destroy your seals in the whole brake.
