Front brake problem

[Irdawood the 2nd]

heya guys

started having a problem with the front brakes recently, well actually the whole front wheel...when i push or ride the bike along it sort of makes a brushing/grinding noise...more so when im going like 5-10mph and brake i can feel feedback in the handles ...its kinda hard to explain what the feedback feels like...almost like a clicking feeling this dont happen when im going at speed....or maybe i just cant feel it as everything is vibrating.?

anyways today it sort of got real bad... it made massive grinding noises when i pushed the bike along and almost like metal grinding together when i pressed on the brake... so i thought the brake was worn...i leave the bike for a bit and just now at night i decide to ride the bike again now the noise seems to of calmed down ....no grinding metal and also the when i press on the brake its ok... its noisy...but no where as near bad metal grinding as it was earlier.... one thing tho if it were the brake pad which was completely worn then the bike wouldnt stop me would it?

at the mo i go at a bit of a pace press on the brake lever and it does stop me (pretty much like normal)

and i cant figure out for the life of me what this grinding noise is from, before was....or what the tiny brushing noise now is... all i know is its comming from the front wheel somewhere

cheers in advance for any help

worn pads will still stop you, but they will grind your discs down a LOT and will make a lot of scraping noise, so thats a possiblity that it is your pads?

if not, then check the caliper isnt catching the disc in any way (the disc could be warped?)

thats about all i can think of sorry

oh p.s. could it not be shagged wheel bearings making lots of noise?? not really sure on that one to be honest, but you'd prob notice a handling problem anyway

i dont know much about handling probs... im new to bikes ...so i really dont have a clue trying to figure out people from up north (near manchester and about) so i can take it to them as they will have more experiance then me, cam (one) has offered to help but we both are pretty much in the same boat and dont know much about the brake thingy.


also the shops areound here want ridiculous ammounts of cash just to look at the bike in the region of £40...and im short cash so that dont help....

if it is scrapping on the disk.... would it still stop me (pretty much the same) as it was stopping me before?

Does the Grinding noise happen continuously when you push the bike or does it pulse in time with the wheel spinning?

If the noise changes as the front wheel turns then its probably a warped disc... not too much to worry about as long as it doesn't get too bad.
If the noise is a continuous grinding noise then I suggest you follow the Brakes faq https://www.bikechatforums.com/viewtopic.php?t=19435

You can inspect the pads to see if they are worn, if they are then change 'em. It explains in the faq how to tell if they are beyond their wear limit.

If not the pads then it might just be the caliper has seized; strip and clean it/them and you'll notice a big difference. Don't worry its not too difficult.

Hi

As he says it could be wheel bearings.

Worn out brake pads will make the noise you describe, and will still stop you fairly normally until they are right down to the metal. Once they are down to the metal you stand a chance that the brake pad backing material will weld itself to the disk and stop the front wheel very suddenly and very permanently

All the best

hmm how would it cost for a new disk as i think the noise is pulsing but im not too sure...it all feels very weird

any of u guys up north so u could lend me a hand in any way please

i think it could be the disk but im not sure i just wanna know the cost of replacement ...approx?

but what i am hoping for as...that its either some crap on the pad...or the pad needs replacing...

what i dont get is why earlier it was making a racket and now its still making some scraping noise but no where near as much...?

[MarJay]

New disc=not cheap. about £60 ish (estimate)

If it was bad before and not now then I reckon its a seized caliper or severely worn pads - possibly both (Not warped disc).
Follow the faq its really cheap and you'll learn about brakes (I hope )


I doubt that it is wheel bearings, cos they take time to get into such a state where they make noise. You'd notice the front wheel feeling funny.

Hi

If you are suspicious about the state of the pads the do not ride the bike until you have checked them. Totally worn out pads = soon to be no brakes at all (and that is if you are lucky).

All the best
