    I'm trying to determine if I can switch over to disc brakes on my powered mountain bike as the stock brakes just dont cut it. after 2/3 good braking times, they are pretty much useless until they are re-adjusted.

    cant tell if the brake in the auction is a universal type that might fit my bike.

    I'm still very green with bikes as I havent been on a bicycle in over 16 years aside from goofing around on the beach with rental bikes.

    the mountain bike I've got the engine on is this one:

    Can you put disc brakes on the bike shown?, Yes. But would it be cost effective ?, In my opinion No. The bike shown does not have disc brake mounting tabs on either the frame or fork, So they will have to be added. Then you will need to purchase either a new rear wheel that has a disc brake capable hub or purchase a disc capable rear hub and have a wheel builder lace it into your old rim. The costs of these mods if you have to pay people to do them for you will far excede the cost of your bike as it now sits. You would be far better off to fide a new bike with the brakes you want and remount your motor into it than changing what you currently have.

    As for the brakes you linked to, They are pretty much standard fair for entry level Disc brakes.

    ok, so what kind of bikes come with disc brakes and whats the price on entry level bikes of these types?? I was wanting to convert over to bicycle with the looks of a chopper but still has multiple speeds as well.

    but at the same time if I have to pay a minimum of like $400 for a bike like this I may as well just get a used moped lol.

    I just cant see myself going back/forth to the gym on this thing with the brakes wearing as fast as they are...even if I slow down to like 10mph before hitting the brakes there's gonna be times when I gotta hit them quick and I actually want the brakes there versus flying off into a ditch to avoid whatever it is in front of me :rolleyes:

    Try quality pads?

    Should be fine with good ones.

    Where did you get that seat?

    got the seat from walmart for $20.

    went by the bike shop and talked with them and picked up another set of cheap pads for now and they are ordering me some nice pads which have three different compound types in them, $20 a set but if they work like I want then they are worth it. depending on how they wear (which is why I went with the triple compound type) I can then pick single compound pads based on which compound wears the least so I'm not spending $$ just simply trying out different pads...

    oh yeah, how loose do you set the pads?? like how much space between the pad and the tire rim??

    only bad thing is I have no clue what these parts remotely look like. can you post pic link (maybe ebay hint hint) of the parts?? I know what #3 looks like but no clue what the rear disc wheel looks like?? I thought it was the slotted disc thing in my #3 link??

    I think this is the first one: (tinyurl link, just click link in there lol)

    if I was using brake pads -- would for sure -- buy THE BEST I CAN GET

    I think soft is better -- could be wrong
    soft I would think would stop better but wear out faster

    I use at this time disc brakes
    been working real well
    hope that when they wear down - I can find proper replacement

    been wondering about reg brake pads such as you have
    will cutting groves in pads help with the stopping ???

    regarding adjustment of brakes
    as close as we can get them -- without rubbing on wheel

    ride that thing Mountainman

    rear rim brakes dont work well with 2 stroke oil on the rim. stock exhaust is just that way. most of your braking should be done with the front anyway.

    yes - hill climber (front brake - best for stoping)
    this is true for the more EXPERIENCED RIDER
    but - for those that do not truly understand dangers of front brake ????

    at our bicycle shop
    we always told newbies to not use the front brake
    on any turns
    roads while wet

    we saw many of our customers come back to our shop
    with serious injuries caused by applying front brake to hard
    over the handle bars -- ect ect

    yes - today I use my front brake maybe 60 to 75 % of the time
    but -- not recommended for all..

    want them alive when
    they Ride That Thing ------------- MM

    wow, something I can answer. cutting the pads themselves wont do any good and at best will crack the graphite compound usually embedded in disc pads.

    you'd want to cut grooves into your rim itself or for disc brake rotors....just use the stock ones with holes. grooves are mainly to remove dust as it forms to help maintain a good grip on the other surface without gas buildup.

    sorry, I just have been into scca racing for the past 10 years. just not familiar with bike terminology/behavior yet :p

    I love my front brakes.
    I always try to set my brakes up as tight as I can get them, I like single finger pull on em for scrubbing a little speed off and being able to stop on a dime with 2 fingers.
    I recall one time I was out riding my Mtn. bike (no motor) and had a child run in front of me. I clamped down so hard on the brakes that my bike went up on the front wheel. The kid stopped where he was like a deer in the headlights. He quickly turned and ran back to where he came from and I was able to let go of the brakes before I went over the handle bars. I smiled at him as I went by and his teacher was very grateful that I was able to NOT hit her student.

    how often do you have to adjust them with them set in so tight??

    that and how do you keep the brake pad brackets from moving on their own causing one side to contact and make a squeaking noise?? :confused:

    only reason I ask is I have never adjust bike brakes before putting the motor on this one as I never really cared before lol.

    yeah the adapter is right.... they are us based and you get quick shipping

    as far as a wheel....
    now that is a great wheelset but for most too expensive. also as far as front brakes this would allow you to use both wheels

    and then brakes... mmmmmmmmmm.....

    if you find the best deals you can like from craigs or ebay then you can do this for pretty cheap

    ok so basically looking at this stuff you posted up, I wont have to swap a fork or anything to retrofit disc brakes as long as I upgrade to the correct type wheel for $$??

    the front adapter thing looks like I just need a wheel with the threaded hub and then put the adapter on the threaded portion and attach my disc brake setup to that and done for the front? why would I have to upgrade the wheel?? couldnt I just swap out for the threaded hub??

    #1 -- the main adjustment is where the cable is pulled through and tightened
    this adjustment should not have to be made very often

    the secondary adjustment is USUALLY found next to brake lever or brake
    this is a finger type adjustment
    this is the one used more often -- for fine tuning of brake adjustment

    #2 -- either loosen brake and pull over to correct position
    or a punch can be used to knock over to corrected side

    slight toe in on brake pads often times corrects squeaking noise

    makes it nice when we ride that thing Mountainman

    the rotor attaches to the six bolt is(international standard) mount on the hub...yeah you could go with the adapter but your putting the braking force on a freewheel thread not the whole hub body and spacing on a front wheel and freewheel hub are different

    Walmart has extra-length brake pads for about $5 and they stop WAY better than the normal ones. I have a set on my bike and have been pleased.

    Get some avid BB-7's, they are by far the best brake for the money.

    For a cheap bike, having wheels built isn't really worth it unless you need something special (like if you bought a NuVinci hub) or if you want to be really picky about your parts.

    Your bike shop can order a pair of already-built wheels cheaper than they can get the pieces separately and put them together. IF you go look online at Nashbar or Performance, the cheapest MTB disk wheels they have are $120-$130 or so, and a local bike shop can't build them that cheap (at least,,, in the USA, anyway).
