HydroBoost Rebuild?

[HighSierra]

Has any one rebuilt there hydroboost unit? Mine is not working the way it used to and the brakes them selves are good and both fluids checks out fine.

If it aint broke, Keep fixing it till it is.

Kirk.........sorry, can't say I've done this........YET! But, I talked to a guy last year who claims he did his. He said that the dealer has an o ring kit. I think he said it cost about 15 bucks. Worth checking out........
