Will it hurt, help or make any difference to pump it a few times with the valve closed, then open it a 1/4ish turn or do I keep just pumping it once?

Give it 2 or 3 pumps, then open bleed valve. Repeat until firmness returns to the pedal then go to the single pump to further chase air from the system. when you get a really firm pedal then tap the caliper with a screwdriver handle to chase out any small air pockets left in the caliper.

I think it's probably a great tool. The check valve keeps you from getting air bubbles into the system. You're really close to getting it done. Pump the brakes 2 or 3 times, keep the lever down, open the minibleeder for a second to let air out and close it back up. Repeat until no air bubbles are seen escaping in the hose. Make sure your reservoir is open and full during this process. If it empties, you'll have to start over. When only brake fluid show up in hose, close the bleeder and remove. Refill the reservoir and seal it. Then do slow pumps until it's firm.
I wish I were there to help. It's literally a 30 second process.

Yes, thanks to you all's way appreciated help, the calipers spread apart. I got them back on the mounts then bled the old brake fluid out so I have new fluid in. The brake pedal feels right. Everything's greased, new heavy duty inner tube, spokes all tightened, wheel seems true/even, new sprocket studs & stud nuts & I cleaned the disc & caliper. While I was in there, I took the top and bottom shock bolts out, greased, Locktited & torqued them. Took the swing arm bolt out & greased it up real good. I even put a zert/fitting in to keep the swing arm greased with my new, heavy duty grease gun. I'm astonished at what this "opposite of a mechanic" pulled off with some awesome help. Thank all of you SO much. That's the good news. The bad news is that I still ended up with the original scraping noise when I turn the rear wheel. It doesn't seem like the pads spread far enough apart. At least now I know where the sound's coming from. The wheel turns fairly free although it'd be more free without the scraping. The brakes stop it completely like they're supposed to and they're adjusted correctly. The front wheel's doing the same thing. Making the same noise. Do y'all think my TBR7 came with bad calipers? Will it go away as the pads wear a little? I only have about 3 miles on it because I don't want to hurt anything. |

The caliper housing bolts solidly to the caliper/brake mount. The caliper/brake mount is solid to the swing arm and also acts as the axel spacer/bushing between the swing arm and the wheel hub. If the axle nut's loosened, the mount slides backwards and forward on that steel, solid nub that's coming out of the swing arm (for chain adjustments). As far as I know, there's no movement. If anyone knows I'm wrong here, please chime in. <<a "wearing in " process where they make some noise>> That sure is good to hear Severely! Is that noise it makes during the wear in process a kind of a scraping sound? If that's normal, I'm feeling real good about it. Again, the front wheel's making the same(ish) noise. All the praise & applause goes to y'all, not me. All the help I get form y'all is the only thing making any of this possible. Hopefully, I'll eventually graduate from my title of "The Opposite of a Mechanic", to "Not No Mechanic". Hey, I guy can dream can't he? |

Any thoughts on this Severely? It does sound logical but everthing you guys tell me sounds logical because it is? |

<<are you sure the reservoirs not overfull?>> I'm keeping it right inbetween the high and low fill lines. Do you think it should be more torwards the low line? I have the reservoir mounted level/horizontal on the frame. It didn't come that way but, to me, that just made sense. Should I tilt it back parallel to the frame bar it mounts to (about 45°)? I'm not noticing any difference from when it was and it was hard to tell if you had too much or too little fluid in there. When I see pictures, it seems like everyone else does. <<how loudly/badly is the scraping sound?>> It's definitely noticeable. You sure don't have to squint your ears to hear it. I suppose I could video it and post on YouTube or email it to you if you want me to. <<Do the brakes allow easy turning of either wheel when released?>> BACK WHEEL: Yes. On the stand, when the brakes are released and the bikes out of gear, it'll only free spins about 1/4 turn, give or take, because the chain and both sprockets are slowing it. Do you want me to unmount the calipers to see if there's a significant difference? FRONT WHEEL: Bear in mind. I haven't taken it back off and greased the axle & bearings yet (That's next.). It'll free spin about 1.5+ full rotations with the brake released. The scraping noise from it is the same sound but a bit higher so not quite as loud. It also gets louder and softer as the wheel rotates as if the disc is a little warped. It almost goes away at a certain point in the rotation <<Do your levers/pedals have free play to allow brakes to release properly?>> Yes. I have the reccomend .5" play on the front brake lever and 1" play on the back pedal. <<Is the sound only heard when the bikes wheels are off the ground with the engine not running?>> No. When it's off the stand & I roll the bike around, you can definitely hear it just as much but you only notice the rear wheel because it's so much louder. Of course, when the engines on, you can't notice it. It's definitely not as loud as the engine. When I first assembled it, after I change out the "break in oil" and re-jetted the stock (didn't put in the two washers yet though), it started right up. It seemed to run and ride just great. With all the noise that was supposed to be happening, you didn't hear the scraping. Either that, or it just rhythmically blended in. I put 3.4 kilometers (or miles) on it and have been tweaking on it ever since. If the pads are on backwards, can I do anything about it? Are they glued on there? |

If that's normal, I'm feeling real good about it. Again, the front wheel's making the same(ish) noise. Just a thought here, if the noise is coming from the front too, wouldn’t you think that rotor rust from not using the bike maybe the cause? If the front and back sound the same my thoughts are you need to drive the bike and see if the noise dissipates. |
