Peugeot Boxer brakes? (1 Viewer)

[Steve Gray]

My front brake warning light keeps coming on but the pads front and back are ok. Is there a link between the hydraulic system and the warning light??
or is it an electrical problem??

Not sure on boxer (and I have 1)but on many vehicles fluid level lights dash warning as does applying hand brake often but not always only one shared light

Cheers oldies
Red light in triangle only comes on with the handbrake on. It's the circular orange front brake warning light that keeps coming on when the brakes are pumped but goes off when you turn the engine off???

That should be the wear limit warning for your front brake pads, ours come on on the way back from Portugal a few weeks back and our front pads were down to a couple of mm by the time were reached home.

Cheers Two. Lights on but pads and sensor cables are good, it's a mystery and it's driving me nuts!!

It could just be that the wear warning wire has come adrift and earthing thus making a circuit somewhere?

As has been said above you need to thoroughly check out the wear indicator cables and where they plug into the harness.
It certainly sounds as if there is something earthing the indicator when you press the pedal.

[Steve Gray]

No, sensor cables are all good with no earthing problems?? Not sure what to try next?

Just to be clear, it’s happening when you depress the brake pedal?

I would disconnect the wear indicators at the point they plug in to the harness just to eliminate them as the problem.

As it’s only happening when the brake pedal is applied then the common denominator is the brake pedal movement;
If it’s still happening you need to start looking at the brake pedal switch and any electrical connection to the master cylinder.

The brake warning light also comes on for low brake fluid levels

Nice one Richard, Which may account for it briefly coming on when the brake pedal is pressed.
Even if the level is correct perhaps the level sensor is in need of adjustment/ repair.

[Steve Gray]

Yep, done that (separate the sensor connectors that is) and it still comes on!! I'm very close to taking it down to the garage (expensive option!!)

It's a different indication for the low brake fluid level on our Boxer.

The one the OP is referring to is the front pad wear indicator.

That's what I thought,would also tie in with pedal movement ,but don't know if fitted to this van

Not the fluid level as if you unplug the sensor connector I get a low fluid message which then goes when I plug the sensor back in??

It’s the use of the brake pedal that pushes thinking directly to the ware indicator circuit. But if the ware indicator is disconnected and it still happens then it must be related to pedal movement,
When a ware indicator is worn down it’s on permanently until it is replaced.

On Iveco I had something odd with disk wear left pad looking ok until removed then discs on both fronts had worn a grove into wear indicators can't remember detail ,but disconnecting wire worth a try

I haven't investigated any brake pedal movement yet, that is indeed a good area to investigate.....

Vacuum??

Vacuum??

I don't think it has a vacuum it's a 2014 model?

It will have a servo assist of some kind
