Hi all,

Having a bit of an issue with the electric brakes on my new gooseneck.

They don't seem to have a lot of bit. I need to set my Tekonsha unit up to 8.5 to get some sort of effort out of them. I only need to set the unit to 4.5 when I tow my horsefloat.

Anyway, I took one of the drums off this afternoon. I noticed that the magnet had some gease on its' leading edge, most probably bearing grerase that's spun out onto it. The actual braking surface appears to be clean. But I'm wondering if some fo this grease is making its' way onto the surface when I brake.

To be sure, I'd like to clean the lot up.

Any suggesitons on what to use? or not to use?

thanks

Brakecleen from Supercrap should work.

Perhaps seals need replacing and a brake adjust or shoes are too worn to grip properly.

Thanks for the tip, I have some Brakecleen floating around in the shed somewhere. I'll track in down and give it a go.

The goosenecks brand new, done probably around 1000k.

Had it back to the manufacturer and had it all adjusted up just after it was run in. But it's still not to my liking.

Replace the seals and use brakeclean on the shoes. Grease is a killer on brakes. Is this unit heavier than the horsefloat and may need more effort to stop it

Hi, if you have the Prodigy it has 3 'power' settings to accodate the weight your are pulling so I would check that out first. I have mine on the lowest when pulling float and the next up for the van. Your EBC instructions will tell you how to change it and how it affects your braking.
The drum magnets and corresponding drum face have to be grease free and of course the shoes and faces.
Another thing to consider is the size of the electrical wires that have been used to wire up the EBC, along with making sure you have good elctrical integrity and earths. Always best I believe to run a dedicated HD earth and live to the battery. (fuzes of course).

You might want to check the connection of the wire that comes out the back of the brake plate to the magnets. Heard of them just being twisted then just wrapped with electrical tape. Solder them and fit shrink tube.

I hate those blade type connectors which have given me problems over the year and I avoid like the plauge now. Don't under estimate voltage drop.

You probably know most of what I have written, but some times the obvious does not stand out. Good luck with your problem and hope I have given some help.

Hi all,

fyi

Took each drum off and found that three had a fair amount of grease on the face of the drum. Looks like the bearings were over packed and the excess grease has been flung out onto the magnets.

Also noticed that only one wheel had brake dust on it.

Anyway, hit them all with Brakecleen and wiped off all the excess grease.

Hooked it all up and the brakes now work very well. Only need 1 more volt on the brake unit to make them as good as the horsefloat.

Once they bed in, all should be fine.
