ABS Modulator - Locked front brakes
Hi,

We have a Td5 with the Wabco ABS system. When you depress the brake pedal, both front brakes lock-up and stay locked.

During initial testing, found both front brakes release when either front hydraulic line is cracked between the caliper and the modulator, but not when the line is cracked between the master cylinder and the modulator. This leads to a potential fault in the ABS modulator, causing the front brake hydraulic system to stick and not release pressure to the front brakes when the pedal is released.

Has anyone seen this before? Is there a known repair?

Thanks,
Don

You need to rebuild your ABS unit. There‚ÄĚs a guy on fleabay in the US who rebuilds them fairly inexpensively as it shared with many other vehicles in the US. I recently brought a unit in from Ireland of all places. You can use the Discovery ABS unit without any issues, just connect it the same as it came out of your Defender. Working great now. Good luck (also I have a core of you want one). Thumbs Up
