Problem with my stainless brake lines
 

Ok, let me explain.

I try to unbolt the stock hose but look tighted very strong even with "degripant oil", any ideas?

In the kit from GOODRIDGE, i have 4 brakes lines but seems I need 6! Why? Because I saw 2 rubber hoses for the rear for each side.

First ask: can stock hose can hold the DOT 5.1 brake fluid?
Second ask: about my brake lines, do I need 4 or 6?

Cheers.

4 hoses all together,2 front 2 back,the back ones are longer to replace both rubber hoses each side,i know ive replaced mine.:)

Thanks ;)
