Tech Talk / YZ dual leading shoe front brake
« on: April 27, 2009, 03:22:17 pm »
Gentlemen,
I am working on repairing a 1983 YZ 250 that a friend of mine recently bought. His goal is to make a nice trail bike out of it, but we have a problem with the front brake, or the cable rather.
We just fitted a new Motion Pro front brake cable and cannot get enough adjustment in the cable at the wheel or at the lever to take up all the slack. The wheel will stop when the lever is squeezed, but the wheel can be made to turn by hand, so we know the brakes will be insufficient whilst riding the bike.
The brake shoes are factory Yamaha and appear to have about 75% of the factory thickness remaining.
Am I overlooking something in the adjustment here? I have been working with bikes from the 70's & 80's for nearly 20 years, but this is the first dual leading shoe Yammie I have dealt with.
By the way, yes, I am from the US.
I decided to ask this question here first because the members of this board seem to be honest, knowledgable, and practical.
I am hoping that some of you Yamaha experts familiar with the early 80's bikes might offer some advice.
Thanks!
