I use P4 calipers on The Heap, they do work well but I'm not sure how much better they are compared to the original goldline calipers. Maybe if I was racing, but with more sedate road riding it's hard to compare. Oh yes I did have to change the handlebar master cylinders too. The coffin resevoir type just weren't up to the job. Mine were off a 749 with integral reservoirs to avoid the Meccano type resevoirs.
