After my Honda VT750 1998 fell down while riding, it started making noise somewhere around the front wheel; noise like two hard pieces are scratching each other. At the beginning the noise happened only when the front brake was applied, but now it happens when riding. I also feel weak knocking on the front brake lever. The pace of the knocking becomes faster as the speed of the bike slower. The brake disc was hot after a ride in which I used the brake.What is the problem and solutions? I'd appreciate answers not like take it to a shop. Thank you.
Your caliper piston is not returning and you are technically riding with your brakes on. You fix it by taking the caliper off...remove the bleed valve and working the piston in and out a few times and a little cleaning would help a lot.
You might, given your additional details, have twisted the forks. But even though the impact was on the other side, first check the disc by raising the front end, and spinning the front wheel and use a pencil to measure the distance from fork leg to disc.
The piston cups are frozen because of the fact there is oxidation at the back of the seals and o-rings that are making them extra healthful too tight.attempt to pry the pads removed from the rotor with a screwdriver (you're able to ought to open the bleeder). while the save had previous motorcycles with frozen brakes we would faucet the caliper with a super ball peen hammer. that could tension the piston cups in adequate to bypass the motorcycle. i do no longer likely propose this methodology, different than as a final motel, because of the flair for injury.
Well, if you fell off, you likely bent the rotor, and now its dragging on the caliper. You could have bent the caliper mounting bracket as well...but more likely to have bent the rotor (if I recall, the caliper bolts directly onto the lower fork tube...so kinda hard to bend that...) Might be the piston sticking in the caliper as well...but Im really thinking its a bent rotor. Solution? Replace the bent rotor with a straight one. Check out eBay for used rotors so you dont have to pay ridiculous OEM prices.
Couple of things may have occurred. The easy one is the front brake mounting bracket is bent and you might need to just loosen all the connections, straighten and tighten back up. The second one is a bit harder as you may have either crushed part of the caliper or more likely bent the rotor. Jack the front end up in a sturdy manner and rotate the wheel by hand than look or feel for anything out of whack. Go from there.
