BRakes and radiator issues, 81 GL 1100

Post by Rangerrob » Sun May 19, 2013 11:43 pm

I recently started riding, and bought a wing. Ive got a couple repair issues, feel free to comment.

The front brakes are soft/weak; I cant say I have 100% confidence in their quick stopping ability. Best way to check the pads? Will a cable adjustment adjust the brake strength or is that just to adjust to preferred "squeeze" level on the lever/

Rear brakes are pretty much non existent as well. I broke the rear brake lever free.....rust, and tore down then rebuilt the master cylinder with the same parts. Again, easy cable adjustment, or should I rebuild the master cylinder? If I rebuild the master cylinder, can I use the old cylinder body? Seems like most rebuild kits do not include the cylinder body.

And the radiator/cooling system... THe previous owner had a switch to turn on the fan, so the cooling system, radiator, & thermostat were not in working order I guess. And recently the switch has gone out; I think that should be a relatively easy fix. But any advice on either the switch or the cooling system? Is it a major hassle and expense to get the cooling system up and running in stock condition or is the switch to use the fan when the temp. gauge creeps up good enough?

Brakes are hydraulic no cables, try bleeding the front and back again also the lines maybe swelling so they take up yoiu pressure to the calipers..= new lines get braid steel around $140 for all, rebuilding with old parts not a good may have a loose fit = less pressure

You can check the thermostat switch by grounding it the fan should come on if it's working, not too hard to replace up front on top of the front case behind the radiator. could also be the fan switch again check by grounding.

+1 on the stainless braided brake lines. My 1100 brakes were vague and spongy, and putting the stainless lines on made a huge difference - without a doubt the best upgrade I did to my 1100.

The old rubber lines give way to the brakes being applied and feels spongy. Go for the ss.
