WASHINGTON— Chrysler Group LLC said today it is recalling more than 75,000 diesel Dodge Ram pickup trucks over potentially defective braking systems.

Chrysler said in a notice filed with the National Highway Traffic Safety Administration that it will recall 76,122 2010-11 Dodge Ram diesel trucks that have a hydroboost brake system with a faulty power steering reservoir cap.

The Auburn Hills-automaker said a buildup of vent pressure could result in brake pedals being slow to return. Brake lights that are slow to extinguish can increase the risk of a crash, Chrysler said.

Chrysler estimates that 1 percent of the vehicles have the problem. The automaker said it has received 175 reports.

In October, Chrysler replaced the power steering fluid reservoir cap with a new one that reduces pressure in production at its Saltillo Truck Assembly Plant in Mexico. Chrysler became aware of reports of the issue in the first part of this year. It's not clear what prompted the timing of today's recall.

The recall covers vehicles built between March 2009 and October 2010. Owners who paid for repairs will be reimbursed by Chrysler.

Chrysler will begin notifying owners in February.

Chrysler spokesman Vince Muniga said the company has no reports of any injuries or accidents as a result of the issue.
