Knocking in front every time a tyre rotation and also ABS light is always on
If you have ABS and that warning light comes on, you should have the system scanned for trouble codes. The code will point you in the right direction to look for the problem.
Could be a faulty brake caliper, or other problem.
SOURCE: abs light on always
Have you checked your brake fluid? It may be low or an indication that the brake pads are worn, causing the light to stay on.
SOURCE: disabling faulty abs breaks. Will car still pass mot?
If there is only one sensor faulty you should be able to replace that one.If for any reason one abs wheel sensor cannot connect to the abs system reader it stopes working.It means your brakes working just as fine but the Anti Block System is not functioning anymore.Your car will certainly pass the mot without ABS.

You actually have two separate problems. The brake pull to the right is indicating the left side brake is not working properly. You will want to remove the left front wheel, collapse the caliper piston and make sure the caliper is floating freely on its mounts.
With the piston collapsed you should be able to slide the caliper inboard and outboard of the rotor. If not, you will want to remove the attachment pins, clean and lubricate the pins. If they are grooved or worn you will have to replace them.
The second issue of the ABS light is indicating the system has detected an electrical sensing or control problem. Take the vehicle to your local Auto Zone or Advance Auto and ask them to scan the vehicle for trouble codes. They will scan it for you at no charge.
Chances are you will find a wheel speed sensor problem at one of the wheels.
Write the codes down and respond back, we can start diagnosing the problem,
Good luck, let me know.
