Rear brake ? Floating?
bob larry:
Is the rear brake free floating or should it be attached? Mine looks like something is missing..
When ever I reverse the bike off the truck the brake goes with and the hose gets it good.
KXcam22:
The rear brake is attached to a slot on the inside of the swingarm. Full floating rear brakes went out of vogue years ago with the intro of disc brakes. In the drum brake world it was often used to keep the dimesional relationship of the brake components equal (parallelogram) to improve braking consistency - but I neve noticed a difference. Strange but my sons 2008 Kona Stinky mountain bike has a linkage to make the rear brake caliper full floating. Cam.
hughes:
The caliper slides/floats on two pins.
bob larry:
Unless I put a tie strap around the swing arm and brake line, when ever I put it in reverse(lol) the brake goes with the tire and pulls the line pretty good.
Maybe the pads are just sticking to the disc from dirt ? Shouldn't be so ?
Friar-Tuck:
Bob,
There is a small piece of aluminum that resembles an "I" beam attached to the swingarm.
The caliper slides on it and then the axle slides through the other end of the caliper mounting . (see cam 22 post above)
I think you may have mis-understood the term "Full Floating".
I by no means am an expert, so please don't take this the wrong way.
This is kind of important as you may lose your ability to use the rear brake... or worse.
If I understand your situation correctly, go out and look at your rear brake caliper. One end mounts to the axle itself. Now grab the caliper and rock it towards the rear of the bike.
(like you were backing up)
look at the inside of the swingarm, where the other end of the caliper was resting,
there should be a that piece of "channel"
That keeps your caliper from spinning all the way around when you apply the brakes.
The caliper body actually has slots that slide on that "beam" and keep it from rotating.
This is why it rotates rearward and pulls on your brake line when you back off the truck...
and when you apply your brakes, the pads apply pressure to the rotor and rock forward hitting the actual mounting point of the caliper....I think... :?
I'll come back and delete this post if I'm all wet...
