Welcome to the forum Ktadej,

YES - I have two ideas:

1. add vehicle details
2. Please follow this link New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum to the New Member Area - Intro a MUST forum and post some information about yourself and your vehicle for all members to see. In return you'll get a proper welcome and some useful advice about posting to the forum.

Thanks for posting the Intro.

Now I know which model you have, I've moved the thread from General Tech Help to XJS forum. Members here with the same model will be able to help.

Ktadej,

Have you bled the brakes, and did you do it using the Jaguar or the Teves procedure?

On my 1989 XJS there is a restricting flow valve just below the abs block.
Mine allowed fluid through but not a fast enough return so the rear brakes locked up. To keep the vehicle on the road I removed the valve and the male and female threads on the brake lines joined together. I eventually found time to open the flow valve and found old brake fluid and crunchy crystals blocking the passageway. Cleaned it all up reinstalled, bled the brakes and no problem since. Of course after writing all of this the above mentioned valve unit may not even be fitted to your car. By the way the last time I checked a new valve is at least a couple of hundred dollars assuming its still available.

1989 Valve Blocks for the ABS on a 5.3 V12 No Longer Available and a Complete New ABS Master Cylinder Actuator also unavailable would be 'North' of £1,000.

 

Suggest you reverse engineer (delete ABS brake system) and go back to the readily available Vac.assist brake system......not sure about the ECU system kicking out codes.. some of the electronic wizards here can comment...also query Lockeed at Jag-lovers as he seems to really know ABS systems. N.A. Lutz in Oz has been doing this on later units that have ABS problems......Best, JW
