bleeding brake is necessity? If so, how long should i often?

And, anyone can tell me how to change old brake fluid to new fluid? I have been the same old fluid since i got my new car. My car mile is over 108 k.

 

It's a good idea to bleed your brakes as brake fluid absorbs moisture and will cause corrosion over time. The process to change your brake fluid is not difficult, but you need to know what you're doing. Unless you have a special tool, it will take two people...one to press on the brake pedal while the other opens and closes the bleed nipple at each wheel. Recommend you find someone who has done it before or buy a repair manual...that will outline the process in more detail.

I am planning to install my SS lines soon so which brake fluid should I go with?

 

there is a web site you can get a deal on SS lines with Motul synthetic brake fluid. I forgot the name of it though. gpracing or something like that, maybe gtracing

 

Also, for bleeding, if you don't have Speed Bleeders, I HIGHLY recommend using a vacuum pump w/ brake bleeding kit (Autozone sells one for ~$25-30, it's made of plastic, Sears has a metal Craftsman pump, forgot how much it was though)

It is a true "1-man" brake bleeding kit. I've used it on several cars with very good results (pedal's tight as a rock )

 

I used the vacuum pump bleeder on my 95 KingCab to renew my brake fluid. It was dark brown from years of being in the system. I used a syringe to remove most of the fluid from the reservoir and poured in new fluid a couple of times. I then started at the furthest wheel from the master cylinder and started bleeding it until clean fluid came form the bleeder valve. Worked like a charm.

I already have SS lines, got them in a GD for around $80. I didnt get any brake fluid though, so I should go with Motul 600 brake fluid or is there something better?

 

Motul 600 absorbs moisture/water really quick, so you'd end up having to change it REALLY often. Its more for hardcore track guys, who change the brake fluid often anyway. If you want something more low maintenance get ATE blue. They say u can go up to 3 years without bleeding or replacing it.
