Hi everyone,

I'm at the end of my tether with my partner's car and Im wondering if any of you have some insight.

My girlfriend has a 2018 (68 plate) Ford focus 1.5tdci. it's on about 50k miles.

Over the last couple of months we've had a couple of issues with the car, firstly the Airflow sensor threw a fault which we replaced. Then a couple of weeks later the o2 sensors which turned out to be the fuse.

Fast forward another month and the electric handbrake wouldn't engage on one side which threw another fault.

While waiting to get this looked at the handbrake engaged while parking one day on the faulty side and wouldn't disengage.

I got the car into a garage and they checked and replaced the caliper and the battery. I've had a call now saying they can't get the new caliper to register with the car. It won't work. They seemed at a loss and are still looking into it now but I feel like the cost is going to be astronomical if they are chasing a fault.

Has anyone had these sort of issues with a focus of this age? Or any other ford for that matter.

I've used the garage for a number of years and have always found their work to be excellent. They are genuinely struggling to get this one diagnosed and fixed. Been without a car for a couple of weeks now and it's causing quite the strain at home not being able to get to and from work for my partner.

I'm losing the plot with the car which has otherwise been great until this point.

Any advice would be appreciated.

Thanks for reading

Hi, caliper should be plug & play, unless you have a wiring fault to the caliper.

To reset caliper:

Turn on Engine

Press hard and hold foot on brake pedal

Engage handbrake and hold button up for six seconds

Release handbrake and hold button down for six seconds

But this must be done AFTER they have bled new caliper and set pads to correct level with foot brake

Thanks for the reply Dave.

I think unfortunately the problem is in the wiring. They could not get the park brake out of Service mode with the new caliper on at all.

Auto electrician has been out and says it's throwing some strange voltages when he's testing it.

I fed this back into a friend of a friend who happens to be a ford tech. He's told me there's a small section of the loom that comes out to the brakes from roundabout where the rear drivers side passenger sits that he has had to replace on 3 other cars of the same age. Loom has essentially broken/frayed and this section had to be replaced in all 3 cars.

It's not an expensive part (they had it in the book at about £35) 

So hopefully that's my issue, I've passed that back to the garage that has the car and fingers crossed they can get it sorted.

Just for info in case anyone else is having problems, there are a lot of Service Procedures in both versions of FORScan for applying and releasing each Rear Brake individually as well as a Calibration test.

Obviously if the wiring is broken then the above will not help much but it may quicken the investigation process.

Hello mate do you know where the break in the loom was? I’m in the same situation
