I just had my B&B out on the road for the first time today and I noticed that the brakes feel a little spongy and seem to pulse when braking. Would warped calipers cause this or maybe the proportioning valve? The front brakes are 9" discs and the rears are 11' discs. I know it sounds backwards but thats how it came from B&B. Also does anyone know if one of the aftermarket 11"
disc kits for mustang II will bolt up to my front end? Thanks for any advice....Jim
