1. The maintenance schedule for my vehicle, a Chevy HHR, does not list anything that should be done at 25,000 miles, however at 30,000 miles there are 2 things recommended. They advise inspecting the fuel system and replacing the passenger compartment air cleaner.
2. The most recent Technical Service Bulletin on my car was May 1, 2008 and was for grinding and/or growling noises in park on an incline.
3.Antilock Brake System
When wheel slip is detected during a brake application, the ABS enters antilock mode. During antilock braking, hydraulic pressure in the individual wheel circuits is controlled to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold, or increase hydraulic pressure to each wheel brake. The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.
Fascinating discoveries! ChiltonLibrary is a wealth of information.
