When I want to change brake lines to stainless steel one, the brake oil will drip all the time.
So can I just fully drain brake oil and flush it after I finish changing brake lines?

Thanks!

 

Keep that stuff from hitting your paint. Brake fluid will corrode your paint.

 

Theres no need to drain it. If it leaks that's fine just do a good flush when you are done. If you let it fully drain its going to be more of a pain to get all the air out.

 

So the oil would not drip that much?
Is it ok to just ignore the oil and replace brake lines?

Thanks!

 

Its going to drip, mainly the fluid in the lines you are removing. Make sure you put an oil pan under to catch the fluid. Make sure you clean it off any paint immediately. Leave the master cylinder reservoir cap on so that the fluid does not flow much while you are doing the swap. Im assuming you have the proper tools to change the lines and know how to flush/bleed the brakes.
