GM China Investment Co., Ltd. is to recall 7,942 imported Cadillac CTS cars in the Chinese mainland from April 28 due to possible brake fluid leakages, China's quality watchdog said Thursday.

The rubber part of the brake lining could trap water with impure chemical materials, which could lead to erosion of the brake lining's connection point with the brake cylinder, a statement posted on the official website of the General Administration of Quality Supervision, Inspection, and Quarantine (AQSIQ) said.

The erosion could lead to possible leakages of brake fluid, affecting braking.

From April 28, the Cadillac after-sales service center would contact customers and help replace the old brake linings for free, the statement said.
