Slash 5 rear brake

What's the secret to adjusting that sucker so that it actually feels like its working when you hit the pedal?

Sand the glaze off the drums and clean with MEK. Relined shoes with a good friction compound. It's also good to disassemble the pivot pin assembly clean and grease. They can get pretty gummy and resist your foot.

1) Clean up the drum and make sure that it's in spec. If the hub is worn out, replace it.
2) Check out the brake shoes for wear and/or contamination If theyre contaminated I replace em.
3) Set the brake lever (The one on the drum.) to 90 degrees
4) Take a look at the brake lever and pin. Make sure those are OK.

Usually poor rear braking is either worn parts or contaminated linings but if all of those things are good, you should be able to lock up the rear wheel.

Love those fenders, man! What are they from? They really lighten up the bike visually. As for the rear brakes, I've never had any trouble with mine, so I don't have any words of advice. Good luck.

I think the answer may actually be in your question. A motorcycle, or a car even, gets most of it's braking effect from the front brakes. It has to do with the Physics. When the bike brakes there is a transfer of the weight to the front wheel. The rear wheel can actually lift off the pavement in severe enough braking. At this point with the rear wheel off the pavement there is no breaking from the rear brake. The Airhead motorcycle can lock the rear wheel with it's drum brake. At this point the wheel skids and braking effect is lost again. As more weight is transferred to the front wheel the rear brake has less effect.

Leaking final drive seals, over greasing the wheel splines, worn out brake shoes. These are the major problems you will encounter. Learn to live with it.

Just the first ride today after reassembly so I still have some adjusting to do. The fenders are from 7 Metal West, really thick aluminum in an easy to care for brushed finish ala Scotchbrite :-)

Ah, more raw aluminum to develop that patina of loving use. :)

Yeah, what they said. Fronts require an incantation akin to that of the Holy Hand Grenade of Antioch.

Or see Duane's article on brake adjustment ;)

Nope, the process is different on gravel and dirt.

I haven't a clue. The flared end was rusted so I cut it off and had the local muffler cat stretch the end so I could fit that Supertrapp disc assembly. That thing sure makes it an easy tune, just pull discs until the plug color looks right.
