KE Laser brakes

[deesun]

I have an 89 KE Laser and the brakes are s**t. Everything is in good working order discs, pads,linings, lines ,no leaks , wheel cylinders are OK, fluid changed recently,bled properly but they are stil crap. I guess they came like that back in 89 but without spending a bomb I would like to improve them. I have not heard any real good reports about swaping the rears for discs and thats a bit too expensive anyways. Anyone got any ideas?

Thanks in advance.
