Tech Tip: Range Rover Conquers Brake Rotors

Customers may report that a vibration or "judder" is felt in the steering wheel during braking. The front brake discs may have worn unevenly, resulting in thickness variations on the disc. The remedy is to install two new front brake discs (Land Rover P/N SDB000201) in combination with new specification front brake pads (Land Rover P/N SFC500050).

Karl enjoys watching classic movies, especially ones involving exploration and adventure. Many of his favorites feature a Land Rover. He can see himself commanding a safari expedition, perched atop his Rover, on the lookout for big game. Unfortunately, the reality of carting kids to baseball and soccer practice leaves little time for African safaris.

One adventure he enjoys in his 2003 Range Rover is weekend camping with his family. Upon returning from his most recent camping excursion, Karl called about a problem with the car. He said that the Range Rover had developed a vibration in the steering wheel, but only when he stepped on the brake pedal. I did some research and found a solution to his problem.

Understanding Coolants

All-season coolant used inorganic acid technology and worked great for almost 30 years.

In the 1960s, coolant was changed twice a year. In the fall, antifreeze with ethylene glycol-based coolant was put into the engine to prevent the coolant from freezing and cracking the block when a cold front hit. Often, if the engine got hot, the antifreeze would boil off. In the spring, the engine would be drained and filled with water and maybe a small can of an anti-corrosion treatment.
