misterroy Posted July 6, 2018 Report Share Posted July 6, 2018 Hi, I am in the process of fixing up a 2003 sherco and the bleed screw at the rear brake is not the standard 6mm. It looks like a 7mm diameter bleed screw has been used, the small hole at the end of it has been crushed to an oval, and the tip looks knarled. I am struggling to bleed the brake. The assembly was working before the rebuild. How easy would it be to rethread the caliper to take a different bleed screw? thanks Quote Link to comment Share on other sites More sharing options...
mcman56 Posted July 6, 2018 Report Share Posted July 6, 2018 I don't know if this helps but I once bought a used Beta that had a round steel ball under the bleed screw of the rear caliper. At the time I did not know if it was OEM or not. I suspect a PO had a hard time getting the screw to seal so added the ball. It did work. I would think the challenge to re-threading the caliper would be ensuring the that the threads were perfectly perpendicular to the sealing surface at the bottom. A ball may help if it was a little off. Quote Link to comment Share on other sites More sharing options...
reggie Posted July 6, 2018 Report Share Posted July 6, 2018 There were some Betas that had the ball bearing under the bleed nipple, this set up was stock for some model years. Quote Link to comment Share on other sites More sharing options...
