    Dunno how you dunkers do it!

    I've never been a trailer dunker because I don't want to have to buy a new trailer and brakes every few years. A tandem trailer with breakaway brakes on four wheels costs a fortune!
    With all the shite weather this year, my boat has been doing a fair bit of sitting around. On the last occasion that I used it, the trailer brakes had seized. Not the disc brake pistons, but the brake pads had rusted and bonded onto the discs!!
    In the process of freeing them up by way of skull-dragging the trailer with the cruiser in low range, I tore the pads clean off the backing plates.

    Today, I had the chance to pull them apart to find that new pads are required all round. cost =$140.00

    I always rinse the trailer thoroughly in fresh water and it lives in a shed. There is no sign of rust apart from the disc drums.
    I know I shouldn't have put it away wet but with all the wet weather we've been having it is sometimes unavoidable.

    This trailer is just two years old.

    At least the pistons are moving freely.

    How do the dunkers keep operational brakes on a boat trailer?`

    There must be an alternative to steel brake DISCS on boat trailers.

    Lot's of fresh water then never let them sit in the 'on' position, this will see them fine for months, they will surface rust and a scraping sound when first towed but it will clean up fast and as long as the slider/pistons are in good order they will be ready to repeat the process all over again.
    Sometimes I will run slowly with the brakes on a little the first km from home to speed up the process.

    This has always worked for me anyway, I am not scared of using some crc etc either but it must be burnt off some at the start of the journey.

    oops just read they are brake drums, thats harder will leave that to those that deal with them, lot's of fresh water is still your only friend... i feel fo you I couldnt even get them to behave even when exclusively freshwater dunked!

    There is a fine line between fishing and just standing on the shore like an idiot

    I wonder how much deeper the ocean would be without sponges

    How do you get a 2 tonn boat on with out dunking it? People who can't drive their boat on annoy me let alone some one who is going to winch it onto a trailer that is hardly in the water.

    Bainbridge technologies in Cleveland make bronze disc rotors for trailers. Calipers also I think.

    I opted for full stainless discs and calipers with my new trailer and it is constructed from I-Beam aluminium.

    It cost me $5764aud which included Titan electric overide break away system and galvanised torsion axles, I brought this one in from the US a few months ago along with my Seaswirl.

    That sounds like a very good price should never have to replace it. I think I will be going alloy on my next trailer in the mean time I will keep coating mine in linseed oil. If you let it bake on in the sun it goes very hard and stays on for quite a while.

    Takes up a lot of time at the ramp. Should be taught as part of the boat licensing course.

    And where did you come up with that bright idea? Launching/retreiving has nothing to do with safe operation on the water so why regulate something that doesn't need it.
