Re: front brakes locking up
I just got my 05 750 and we have no probs with it I knew it was a fixer upper so I bought it bad tires and a few other kinks. . . so we get new tires noticed by accident squeezed the front brakes when tire was off the front and the pads didn't really clinch together me and my buddy were scared so we put the tire back on and bled the all the points notices a lot of air coming out the thing was before we discovered this i was using the brakes and they were "working" for an inexperienced rider prob didn't recognize yes i noticed it was choppy but i assumed bc the tires. either way so order new M/C and we take old one apart and notice the spring is a lot cruntched as the new one so im assuming its because that's old been used worn down so we do everything bleed brakes so no air in btw we clean out all the lines everything. so my guy helping me says let me go for test ride and about 2-3 miles brakes lock on him and he tried reengage the brakes and the wont budge he bleeds them and they work again so we come back and thinking pistons might need lube we bleed again and again and i go out 6-7 miles in i start smelling odor my front start bobbing and i pull to side and my brakes lock again . I m confused ive read this post from beginning to end and yes i do have after market levers from previous owner just ordered new rotors bc mine are black/brown now im just asking for suggestions might be the case we are checking the lever later today but if that's not the issue what would prob be the next thing to check
2 full stops
Holy fuck that was hard
Like 1/4milecrazy said, dodgy levers for you sir. If the lines were full of air before, I don't think the shitty lever would have been able to do the usual thing they seem to do, which is where the brake drags as the MC plunger doesn't sit properly in the pivot hole. The fluid heats up and the brakes drag and eventually lock.
Go here Brakes locking up when riding? New LEVERS? Read here PUBLIC SERVICE ANNOUNCEMENT!!
You bled it, go for a ride with proper working brakes, and the front locks up.
Being that you say something about getting levers off Ebay, I would say it is the levers causing problems. Get a nice set of levers from a reputable company like FP, Pazzo, ASV, CRG, etc.
Nissin is the stock MC btw
