Odd electric brake problem - HELP
Permalink  

Hoping someone on here can offer some guidance.

Having an issue with the electric brake on the driver's side on our Jayco Starcraft Outback single axle (passenger side has no issue). After a bit of driving the driver side brake "sticks" when I apply the brakes (too often, but not 100% of the time). The only way I can release it is to back up a few inches.

I pulled the wheels off and cleaned everything up and lubricated the pivot points after the first occurrence.  Yesterday we drove some 200 kms with no problem then it started up again on the way home today after some.  Had driven another 100 kms before the issue started again.  Interestingly the issue has started on both occasions in the same town - our Bermuda Triangle!.   

The van has only done a few thousand Kms and taking it back to the dealer is a bit of a problem as they are a long way away. It has only occurred on the last couple of outings - we were away for a couple of weeks a few months ago and no problems during that trip.  No changes to the van since then.

Going to check the earthing for that side tomorrow.  Any other suggestions welcome (apart from staying away from the town where it seems to occur).

Thanks in advance.

I would check the brake adjustment on each wheel.

Possibility of backing plate not centred accurately.Possibility of a backing plate being damage. Possibility of brake shoes fitted incorrectly i.e. leading shoe fitted in trailing position and vice versa.
The problem doesn't sound electrical to me as power is only on to the magnet when the brake pedal is pushed. Only one lead feeding two brakes so it is power on or power off for both. Suggest wheel bearings are inspected and readjusted too.It often helps to champher the leading ends of the linings of each shoe with a sharp file. If you have just purchased the van then it would necessarily be fixed under warranty.

Hi Moose had the same issue. Had the adjuster backed of to far ( some one told me to back of 12 clicks) and the square section that the magnet pulls on at the top of the brake shoes rides up onto its edge and sticks. I adjusted brakes to locked and then back of three to four clicks or until the wheel when spun rotates about three turns then stops.

 I always back off 10" & 12" brakes 12 clicks. It's important to make sure you  only go one notch, on the star wheel, at a time. It's easy to move the adjusting tool a couple of notches rather than one.

I'd imagine if there was some type of rough surface or damage on the square section you talk of, sticking could occur. It stands to reason the further the adjustment was backed off the easier it would be for that square section to stick.

Cheers Pete

I The method I use is to adjust the shoes up until they start to lock onto the drum, and  then back the adjustment off until the drum starts to spin freely you will will just hear a slight scrapping sound on the wheel,to me this is the best way and its worked well for me over the last fifty years..

 Ron ... Exactly my experience over a similar period

... Until I had problems (poor breaking power) with my recently fitted backing plate with shoes/magnets/bearings etc & drums.   I went to a Trailer Brake Specialist & he was adamant the this was incorrect.   He adjusted them using the 13 click method & FIXED my problem as I watched (& happily paid him $100 for the lesson).

Back to the OP ...  chamfering the leading edges sounds like a good first step but I would talk to the dealer's service workshop to get their input.
