Checking the wheel cylinders on my front wheels, the body is a little bit corroded, well, a bit more than a little bit, it's pitted evenly. What is better functioning a rebuilt cylinder or a new one. The question arises, since I don't know if the new cylinders are of good quality and not Made in China quality. I live in a place with a lot of hills and loosing braking power with a 2 ton monster might not be funny.
