A SIX INCH C-CLAMP, PURCHASED AT THE AUTO PARTS STORE, IS NEEDED TO PUSH THE PISTON INTO THE CALIPER AS LONG AS IT IS THE FRONT BRAKES THAT YOU ARE WORKING ON. IF YOU ARE REFERRING TO THE REAR BRAKES, THEN THE PISTON MUST BE TURNED COUNTERCLOCKWISE(TO THE LEFT). HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR USING FIX-YA. GOOD LUCK

05 chrysler 300 code u1120 and u0121


Both of these have to do with the ABS system. U codes are lost communications codes from computers. Sometimes they are the wires. When you have different computers not communicating. Since yours are both from the ABS, I suspect the ABS module has died. Still could be the wire though (not likely). Check the wire for resistance. if good( less than 5 ohms) then the module has died. When you have ABS system malfunctions, the brakes revert back to the old system. Meaning if you hit the brakes to hard, they could lock the tires and have a skidding effect. BUT the brakes still work, they will stop the vehicle. Basically it is your call to have them fixed.

Hello, I have a problem with my Saturn Astra 2008,


U0121 Lost Communication With Electronic Brake Control Module

As with most trouble codes, the U0121 code gives a general diagnosis. Review the info on this link. Look through the service bulletins. The problem could be a loose plug or faulty wiring to one of the modules or between modules that are listed in the article. I hope this helps somewhat. Good Luck......

Steering light came on a 2006 jetta 5


Hmm, Your vehicle does not have a typical hydraulic power steering system, instead it has a electric actuator that assists the steering.

Get your vehicle (VAG-COM) scan for codes and post the VW fault codes or do a forum search once you have the fault codes.


You may possibly see the following codes:
  • 01309 - Power Steering Control Module (J500)
  • 004 - No Signal/Communication - Intermittent

The steering light will be only two colors, yellow or red (in your case yellow):

Yellow means there is an issue with the system and it will run at reduced voltage when it can but you will still have assist.


Red means there is a serious issue were the system can not give you assist and you should not attempt to drive it like this.


The yellow light can be cause by many things, but most common is a low battery. When the battery voltage drops below 11.7v or so, the system stores a DTC and illuminates the icon to inform you there is an issue with the system and it may work at reduced assist. Since this system is so heavily dependent on a good charging system and battery.



Again I suggest drop by your local dealer and have them scan the Steering Module to see why the light is on.

Power steering prob.lights come on



Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Hi there:
DTC U0121 - Lost Communication With Anti-Lock Brake System (ABS) Control Module


If the fault come back again, this is being caused by a failed ABS module. You will need to replace the module and run the verification process to correct your concern. To run the verification process you will need access to a full level scan tool (as factory scan).


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
