Ok, I have tried time and time again to bleed them, followed YouTube, talked to friends, etc even bough disc cleaner all to no avail they just don't work the way they should!!!!!
Before I go to the LBS and spend loads to get them to work, can someone either look at them or tell me where I'm going wrong. I live in Milton Keynes and work in North London.
So I GIVE up!!!! : (
New pads? what are the symptoms - waht is wrong? What make of brake?
No using existing pads (do have new if needed) cheap Shimano M486 pods.
When braking the just talk ages to stop, i cant even skid ( i dont do),even by pushing the bike with brake on it dose not stop, when the bike was new the disc just stopped, dare I say stick.
Does the lever feel normal or does it come back to the bar? What changed whenthe brakes stopped working
Assuming the lever feel is normal
1) possible contaminated pads. Clean disc thoroughly with detergent and water or degreaser. Then clean again some brake cleaners actually contain a bit of oil
Fit new pads
align callipers properly
Bed in properly
2) stuck piston - check both pistons move as you pull lever - if not remove calliper from bike, remove pads -pump lever holding in the pad that moves to force the stuck one to move - only let it come out a bit - you don't eant it to pop out totally. Lube witht eh cotrrect fluid - mineral oil for shimano. work in and out a few times,
fit new pads
align and bed in
Pads may be contaminated with oil.
Change pads and give rotors good soaking with brake cleaner, then a good clean with hot soapy water then rinse with clean water
Ok, pads changed and this may have worked, fingers crossed
If pads are contaminated can they been cleaned or are they ready for the bin.
If the lever is tight when pulled and does not reach the bar then contaminated pads sounds favourite. Did you have them well out of the way when you bled the brakes? Contaminated pads can be cleaned by baking them or heating with a gas torch or similar apparently. Never tried it my self. Isoprpyl alcohol will sort the disks of any contamination. bedding in new pads will help ensure a good working life from your new pads.
rake fluid, oils and grease are the death of pads as rule of thumb so keep then well apart.
Bin them sorry
Sometimes pads can be saved by burning them / scrubbing them / sanding them
Clean your discs as well to prevent contaminating new pads
