What is Steering and Brake overhauling? Case Wagon R 20,000 km
Background: First time car owner.
Car details: Wagon R
old 2009 July model
20,000 km run.
Issue: During the 30th month scheduled and first paid service i was advised to do steering and brake overhauling.
Now i have no idea about whats wrong and what they intend to do and billing as i have been driving for last two and a half years only and have no technical knowledge.
Personally i dont find any problem driving apart from a sort of radio type beeping noise at high speed from time to time and snoozy sound at low spped at times.
Please explain to me the process of the said overhauling and was it too early for that for a vehicle that has only done 20,000 km.
