replacing the rear brake

[89eliteR]

so im testing my bike out and practicing emergency stops. i get up to a decent speed of 40km/h and then firmly apply both brakes equally. when i do this the * end of the bike lifts up every time. the front brake seems to grab very well where the back does not. when i apply only the back brake it does not seem to lock up but make an almost grinding noise. i ordered new rear brake shoes but i want to make sure im going in the right direction, and the difficulity of installiation on a 89 elite r.

Greetings:

Motorcycles get 70% of their stopping power from the front brake, according to the Motorcycle Safety Council. Under deceleration, weight shifts forward and the front tire's traction increases while the back tire loses grip.

"Almost Grinding noise" is almost certainly abnormal, however. A look at the shoes is mandatory. Replacements are cheap.

i ordered a set of shoes for 21 bucks. im wondering if replacing them will be difficult or something i can attempt myself.

The rear wheel nut can be a bee-yotch sometimes. The Miracle of Leverage has always served me well. Use a SIX-Point socket; 22mm or 7/8ths if I recall correctly. You might have to remove the exhaust first.

The Factory Service Manual for your scooter is in the Manuals section. Download and read before you decide to attempt.

22mm nut holds the rear wheel on. i've always had to take the muffler off to get to it w/ a socket wrench.

the trick to getting it off easily, is not to stick a metal bar between the spokes and just go at it.
just set the rear brake, put your socket wrench on, and smack the wrench w/ a hammer. it hasnt failed me yet; ive taken off rear wheels from 6 different bikes and this has worked for me every time.

sounds violent and fun. thanks for the help guys.

From the looks of it the exhausted would need to come off. With that being said. Would I need any sort of gasket when I put the pipe back on?

[fightingplankton]

i dont use a gasket, just dont lose that little metal ring that sometimes stays on the pipe, sometimes in the cylinder.

[evilone]

That little metal ring is the gasket. New gaskets compress and they should be replaced whenever pipe is taken off but i have also re-used.

So my new brakes are in today, and im getting everything ready and since im removing the exaust is there any minor mods i can do it before i put it back on? I noticed 2 screws randomly on the pipe near the top. now do they restrict anything? I also read somewhere that you can drill a certain area to get some juice out of it.

here is a better look at the screws in question:

so the brakes do not seem to be worn, but still doesnt explain why i hear a noise when only the rear brake is applied. It sounds like its only grabbing a little bit and not fully. here are pics of the brakes. Besides the cable are there any other adjustments?

[fightingplankton]

those 2 screws used to hold on a little metal heat shield of sorts...doesnt really work, blistered the * out of my thumb on it once.
not really needed.

So i can leave them and it wont affect performance really. Now with the pipe off is int there something i can drill out?
