I sold two nos 17mm ATE master cylinder. Buyers mechanic says seals failed. Need bench test to confirm that. Have overhaul kit to get seals from for replacement. Called PMB but guy on phone not able to say IF they could test them.

Generally not something they test as its not recommend to rebuild them anyways. Most people know when they are bad so its not a common ask. May be able to rig something up but its probably easiest to just throw them on a car. Did they specify in what way they failed? Leaking externally? Not building pressure? |
