Want to DIY for brake systems
 

can anyone help?
I have searched everywhere nearby but am unable to find a suitable diagnostic device for brake systems, a dealer recommend me the V-CHECKER V102, but I don't want to purchase on the internet, I fear that there will be quality problems. does anyone have one or know where I would be likely to find one?

brakes are pretty simple.

why do you think you have problems? what are the symptoms?

The brake seems be a bit loose, some times I get it tight, but it also loose after a few days , I think if have some problems on the brake system

The parking brake or service brakes? Do you have disc or drums in the back? Automotive Braking was one of the few classes I passed in college I can try to help you as much as possible.

Many brake issues are not electrical and therefore don't need a scan tool. I did not understand your problem but I did find a diagnostic scan tool for anti-lock brake systems, which I think is what you are looking for.
