Abs breaks come on last 5 feet when stoping on dry payment

abs valve power relay circuit failur,this is what the code c1266 meens,hope this was some help,all the best.

It sounds like you have a bad wheel-speed sensor and the ABS computer is thinking a wheel is locking up when you try to stop and engaging your ABS system.

Check with a code reader or scanner, the ABS could be at fault

Normally when your abs light comes on, that is referring to your breaks. This could be low break fluid, leak in break hose somewhere, or need breaks checked. Most cars now a days, have a sensor that is part of and hooked up to your breaks, and that will trigger your abs system (which is breaks) and let you know if your pads are low, or to the ware mark. So Here is what you first do, is check your break fluid and make sure that resavor is full, check under car to make sure there is no leaks, under car and inside each wheel area where breaks are, and then next step, is Les Swab can check your breaks for free and let you know if your pads are down to the ware mark. Let me know, Mike

Sometimes this can happen when your break fluid is low, so I would double check that first, but usually if the ABS and Brake warning or flashing, or staying on, you are in need of break service on your vehicle. It may only need new brake pads, but you should get it checked as soon as you can.

In the meantime, try to stay mindful to give yourself extra distance for stoping.

I hope this helps.

It Sounds Like Your ABS Channels, Its A Separate Hydraulic Circuit That Feeds Out To One Or More Wheel Cylinders Or Caliper Pistons.Anti-Lock Brake Systems Can Have From One To Four Channels.

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.

Hi take the front brake rotors off and then remove the ABS WSS(wheel speed sensor) from the hub bearing clean the rust/corrosion from under the sensor and the hub bearing then apply a small amount of grease reinstall your sensors (carefull not to break the sensor they break easy) reassemble the brakes that should fix your ABS concern

did you check the alb sensor? You might also have the "return spring" stuck in the emergency brakes. Sometimes they break causing the brake to lock, which in turn activates the alb. Also, check the brake oil level, in some cars alb dont work properely if the oil level is too low. Good Luck

get mechanic to check and change offending part as experience is required to do it,just check the pipes leading to it in case theyre loose
