Got the four new brakes from etrailer yesterday and set out to put them on this morning. As I said previously, the offending brake had NO shoe left AT ALL! So I started with that one. All new seals and bearings to boot. Up on the Trailer Aid, swapped the brake, no problem. On to the rear brake
PERFECT! NO wear and even a little rust on the drum inside!! Third and fourth brakes the same, NO WEAR. Luckily, I have never had to jam on the brakes.
With DSO's help I read out the power with the multi-meter, but let me tell how the wires run. Main power comes from the controller to the street-side rear brake, back to the front street-side (the offender) also from street-side rear over to curb side rear then to curb front. Funny but it works, or so I thought.
Max power output from the controller is 4 volts. At the offending brake I got 3.6v, the other three had less the 2v
. Cut all the wires back, re-striped them and rewired each brake, taking reading at each brake. All are now reading 3.6.
That means that for two years I've been stopping with ONE brake only! SCAREY!! Result-- I now have three almost new brakes with almost no wear. spares?
And a brake system that works correctly.
Just have to road test and seat the shoes. Also, new bulb seal arrived today with new guide blocks. So we'll have a bug or two in Wakewa Springs next week.
