I’ve never gotten on particularly well with both sets of Juicys in the PJM household. Initial results are good, there’s plenty of braking power and feel.
However, I soon encountered the awful lever-to-the-bar feeling and general mushiness, the pistons refused to retract properly and the lever shape began to grate for me.
They need a lot of TLC, you need to regularly clean the calipers to ensure that the pistons don’t clog with brake dust and frequent bleeding is a given.
Otherwise, you could buy a set of Shimano brakes off the shelf and expect excellent performance and hassle free bleeding on the (rare) occasions when they need it. In ten years of running Hopes, I’ve never had a problem, aside from a single loose banjo but the resulting rebleed was simplicity itself and I prefer the lever shape to boot.
