Brake booster (hydraulic) and master cylinder (1993 P30)
The brakes on this thing are on my "do list." They were scary to drive with. Barely adequate to bring it to a stop, definitely no such thing as an "Emergency stop" within possibility. We drove it home from the previous owner on mostly empty roads on a weekend, and I still felt somewhat unsafe.
Looking at the system, I'm seeing the hydraulic brake booster is leaking fluid (power steering fluid) fairly profusely. It "marks its spot" when you park it. I haven't dug into the brake lines and master cylinder yet. The pedal required a lot of force (like the booster wasn't boosting), and still felt kind of spongey (like there's air in the system or maybe a fluid leak). It's getting a new or rebuilt booster and master cylinder at this point.
Has anyone used Prior Brake Products? That's the rebuilders/service that RockAuto.com offers for these hydraulic booster units and master cylinders. It looks like they want ~$160 for "return and rebuild service" for the hydro booster only, and ~$190 for the same "return and rebuild service" for the booster and master cylinder together. If I understand the process, you send yours in, they replace seals, test and fix anything else and send your exact unit back "remanufactured."
It looks like I need to know a RPO code and/or a "pedal rod code" when I order/send the unit in. RPO codes brings up another interesting question. Where is the SPIDS on this chassis? It's usually in the glove box on most GM Vehicles. I haven't found a glove box in this one, so I don't know where they might have stuck the sticker.
