No.
BMX bikes have rim brakes, they work by pinching the rim between two pads. The surface of the rim will wear away eventually, there's not really any way around that. Best you can do is keep the pads and rims clean from any embedded grit.
If you're really stubborn, you could have a BMX modified to take disc brake wheels, but it'd take some serious metal working skills.
Or you can replace the rear wheel with a wheel that has a coaster braked hub.
Depends on what it is and what you do to it. If it's really paint, it can chip and scratch if you bang into stuff, but you shouldn't be losing big flakes of it unless the job wasn't done right to start with.
If it's anodized, etched right into the metal, it shouldn't come off ever, apart from along the brake tracks.
No it's pointless unless you have a race bmx which doesn't have a front brake anyway
if you squeeze the lever slowly, the bike will brake slowly.
you take the paint and put it on the end of the bike first and work your way up !
The purpose of the brake is to stop the bike from moving so it is really hard to move a bike when you put the brake on.
I would assume u cod use a Paint for plastics thAt would infuse with your cables and be successful just clean very well and don't use acetone it might eat cables
depends if you are wearing the protection for a dirt bike that is needed
No because the bike would brake evry time so no
Friction is what ultimately stops your bike
Sure. But it's a tough environment, lots of mechanical wear. It'll be hard to get the paint to stick.
This type of brake is called a coaster brake, or a foot brake.
If it's a disc brake bike, then Rotor is another name for the brake disc. If it's a BMX rotor may be another name for gyro / detangler - the thingy that lets you spin the bars on a brake-equipped bike w/o making a mess of the brake wires.
The front brake of her bike was broken.
