Master Cylinder adjustment seems to fix everything? 🤷🏻‍♀️

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. I appreciate that you're trying to keep this vehicle together after 30 years, and that some things are not perfect. However, when you have multiple variables of things that don't work right but are somehow left to be acceptable -- it really makes it hard to narrow down what may be causing this latest concern. As a rule, the recommendation is to "fix what you know to be wrong" and then go from there. Testing should be performed to determine what is causing the ABS light to come on. Also, a good physical inspection of the steering and suspension is in order. You sure do not want to risk anything fracturing! Since you mention the master cylinder, a tiny hunch I have is that you could have a vacuum leak affecting multiple symptoms here. Although it should not matter by taking the cap off, I suppose there is potential that it could affect vacuum of the engine which can cause poor running. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
