The brake shoes and spares listed here have been or are being used on most trailer and caravans on the road. Very old Lockheed brake parts we're discontinued many years ago and most parts for these brakes are no longer available.
Most parts on a brake back plate are replaceable but should more than a few items be required then it may be worth replacing the complete backplate with all the brake parts attached. Unfortunately, Al-ko don't recommend the backplate is replaced so they don't offer this as a spare part.
Most braked trailers and caravans are fitted with either Al-ko, Knott or BPW brakes.
Al-ko introduced the flushing kit as few years ago and it has proved to be very popular, it extends the life of all the brake parts as well as the brake drum. These are mainly fitted on boat trailers as salt water and brakes just don't mix.
