Before Daytona crash, Ryan Newman was outspoken critic of NASCAR danger

LAS VEGAS — This we know: Ryan Newman might very well be the toughest man in NASCAR.

The Purdue graduate with an engineering degree has, for 18 seasons, railed against the dangers of superspeedway racing. He’d been airborne in his car too many times for his comfort, and his scathing criticism of NASCAR’s approach to racing at Daytona and Talladega got him fined for his bluntness.

Now he has a head injury from yet another airborne accident, this one on the last lap of the Daytona 500, and his streak of 649 consecutive races ended Sunday at Las Vegas Motor Speedway. He could have been killed; in a statement, he intimated he understands it should have been a fatal accident.

Cadillac Celetsiq, Lyriq GMC Hummer and other future GM electric cars detailed

The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built

Symptoms of a Bad or Failing Brake Master Cylinder

The brake master cylinder is one of the most important components found on modern car braking systems. It serves as the main valve that pushes brake fluid through the brake lines so that the brake calipers can squeeze the pads against the rotors. It functions by pushing a metal rod through a cylinder to force fluid through the braking system to the wheels. One end of this rod is attached to the pedal and is actuated when the pedal is depressed. Usually a faulty brake master cylinder will produce a few symptoms that alert the driver that service may be required.

1. Abnormal brake pedal behavior

One of the first symptoms commonly associated with a bad or failing brake master cylinder is abnormal brake pedal behavior. The master cylinder is the component that generates all of the pressure
