So I was talking to the mechanic who fixed my "other" problem and he mentioned that the brakes are really grabby. Meaning that (especially the driver rear) with catch hard with a slight brake tap. And said that most likely the lines were collapsing and needed to be replaced. Also said it could be the cylinder in the rear leaking a bit and causing the grip.

So question is, how tough is it to replace the lines? I have done a ton of brake jobs just not a full line replacement...

Any other suggestion as to what it could be?
