New Consumer Reports testing reveals that a Graco-brand double stroller could pose a safety risk.

The problem was discovered during braking tests for Graco’s Ready2Grow Classic Connect LX stroller.

Testers put the stroller on a tilt table and loaded it with 35 pounds in the front infant seat and 40 pounds in the back seat.

The table was then slowly tilted up to an incline of 20 degrees. The brakes gave way, sometimes at 18 degrees after the plastic teeth used to lock the wheels bent.

No injuries have been reported related to the stroller's brakes.

Graco says that Consumer Reports' test "fails to replicate real world conditions" because of its steep angle and that the stroller meets voluntary safety standards.

"Our rigorous test is designed to gauge whether strollers have an extra margin of safety. We've tested more than 160 strollers listed in our current ratings,” said tester John Galeotafiore.

“This is the only one, including double strollers, where the brake released. And we're also concerned that the brake teeth bent."

Consumer Reports has labeled the Ready2Grow Classic Connect LX a "don't buy," along with other Ready2Grow strollers with a similar brake design. Those include the Classic Connect, the Click Connect LX and the Click Connect.

If you own any of these Graco strollers, ask your retailer for a refund.You can also call Graco's customer service at 1-800-345-4109.

Consumer Reports says several other Graco strollers earn top scores and are recommended.

As for other double strollers, Consumer Reports recommends include the Phil&Teds Navigator for $650 and Uppababy Vista with Rumbleseat for $985.
