Rear brakes stopped working on my '06 4.8is
Local shop replaced master and booster and still no dice. They're saying to replace the ABS pump next, but it's $tupid expensive so I'm hoping someone is doing a partout and can sell me a working pump+controller pair. If this doesn't fix it I'm just going to push the thing into a river lol. Thanks!
