mucka Posted August 13, 2013 Report Share Posted August 13, 2013 Hey all, new to this kind of riding. I brought me a cheap second hand onza t-mag with hs33 rim brakes. Come to bleeding them, done the front no problem. The rears ...pain in the arse, so brought new hose fixings thought it was those, fianaly just found out the problem, one of the rim blocks which has 1/1 on, seems to be blocked. Iv tryed tapping on the side and nothing, tightened the tube in the hole , blowed down and nothings coming through just solid. This happened to anyone, or shed any help Thanks all Quote Link to comment Share on other sites More sharing options...
isitafox Posted August 14, 2013 Report Share Posted August 14, 2013 Not entirely sure what you mean by a rim block but I'll assume you mean the piston in the caliper has seized up. If this is the case then remove the pad and grap the pin the pad clips on to with some pliers and pull it out. Give it a really good clean with some wd40/gt85 and a toothbrush (might require a 2nd pair of hands to help you) and then with any luck it should be freed up.

mucka Posted August 14, 2013 Author Report Share Posted August 14, 2013 Yes thats what i mean..sorry i pulled piston and seems to be ok. But the two threaded holes on top i put a tube on tryed to blow dowm and seems solid/blocked. So tryed on my front brakes done the same with tube and you can feel air passing through Quote Link to comment Share on other sites More sharing options...
isitafox Posted August 14, 2013 Report Share Posted August 14, 2013 Can't help you with that one, might be a case of replacing the entire slave cylinder Quote Link to comment Share on other sites More sharing options...
