I recently purchased a 1996 Blaster which the rear brake assembly has been "upgraded" to a hydraulic disc brake assembly. Unfortunately it is not working properly. I was curious if someone can please give me some feed back. I've read some mixed reviews on weather or not they are worth it. Giving the fact that I have an existing one, I was thinking about fixing the current one. Or buying a new one. And with that, could anyone recommend any one assembly? Thanks in advanced!!!
