I'm changing my front brakes tomorrow and thought of changing the brake fluid at the same time. I know it hasn't been done in a while and the brakes are a little spongy and would like to sharpen them up. I know the method of just sucking out the fluid in the reservoir, replacing with fresh and then bleeding all 4 calipers. Is there a set way of doing this like offside rear, nearside rear and so on or do you just do it one by one ? Also is this a very thorough way of bleeding the brakes or is there a better way?
