Front pads

I've just replaced the front brake pads on my yamaha sr125. Since replacing them the front wheel is pretty tight, eg it won't just spin. Have to put a fair bit of effort in. Is this normal? or should it loosen off? The caliper was pushed right back so i know that aint the problem

sounds like you either not got the spacers in the right way round , speedo unit ( where the cable goes to not sat correctly look for the lug and groove on it .... or you have overtourqed it ( too tight on spindle nut )

thats fine, knew what you meant anyway. I was just thinking there tho. took the bike for an mot with the old pads on and it was fine. When i put the new ones on, they were a bitch to slot over the disc. Didnt change anything else

sorry i just realised that you not had the wheel off ...


sorry my fault so please ignore the above


it may just be the pistons then on the caliper are a bit sticky on the ends of their travel ( unless you cleaned them before pushing them back in ?) and thus holding the brake on a bit so it may free it self but i would recommend remove and refit with a good clean just to make sure and a small amount of copper grease applied to the metal to metal contac of pads and caliper as well as the sliders and caliper piston ( you can clean this with wet and dry paper to get rid of any rust pits etc ) to aid movement

yeah thats a plan. Done it in a bit of a rush prior to starting nightshift last week. So i'll try that tomorrow. Had nothing but trouble, but what can i expect when i pay buttons for a bike that needs work. Still worked out cheaper than buying a spot on one tho. And will do its purpose of a learner bike for me :)

Right, Ive been down and checked it all. Everything is torqued correctly. Piston is in as far as it will go. However, the pads are still binding on, making it quite tough to spin the front wheel. I removed the upper shim, and it was fine! obviously this serves a purpose tho so i popped it back in. I know have the further problem of, the Bleed nipple has sheered off! luckily, (or not) it has done it in such a way that the plug is still intact, however i think it will be a tough job to remove it! Anyone know what size it is, and also a way of going about removing it?
