LIBRA New 12" x 2" Trailer Hydraulic Free Backing Marine Brake Assembly Pair Set - 21020

This drum assembly kit is the easiest way to replace rusted out, worn out, or overheated brakes on a boat trailer equipped with 12-inch drum brakes. There are hydraulic surge brakes that operate on pressure. A new pair of shoes, new springs, and new hydraulic cylinders are installed. Cast iron cylinders rust out more quickly than aluminum cylinders because aluminum is a harder material to work with. No matter how carefully you flush out the drums with fresh water, if you are launching your boat in salt water, you won't be able to get your brakes to last more than 3 or 4 years before the salt destroys the internal parts. It is possible to replace the shoes, springs, and hydraulic cylinders individually, but disassembling and recalibration are methods that are more difficult In order to assemble shoe brakes you will need to use brake spring plier tools, which you will need to purchase if you do not already have one. Additionally, you won't benefit from any significant financial savings. If you feel like rebuilding your shoe brakes, just get this kit and leave it to the backyard mechanics who are young enough not to realize that there are a million and one other things to do on the weekend than struggle to do it Assemble the springs and retainer clips on the Despite the fact that it requires some physical effort to remove the wheels and brake drum, installing the kit is not difficult. If the brake shoes are stuck to the drum, then you might run into trouble. When an old hydraulic cylinder is rusted out, it prevents the springs on the brake shoes from retracting - this can lead to the brake shoes sticking in the system. In the event that you've experienced a brake fire on your boat trailer, this is the reason. The shoes on the drums are seized up, so you'll have to employ a drum puller if you can't pull them by hand. *BTW *BTW It is always recommended to have drum brakes cleaned and reassembled before replacing them with this kit When you buy this kit, make sure you buy the grease seals that go with it Your wheel bearings may need grease, or you may need to replace them if they are visibly pitted - or if you are performing this repair due to a brake fire. You can still do it even if you have to reapply It is not necessary to buy new seals if you are using your old wheel bearings. As a result, the seal has to be removed to remove the inner bearing, and this cannot be done without damaging the seal. There is one 14 ounce tube of grease required for each axle, so you will need to purchase Marine wheel bearing grease if you don't already have any. Please be aware The wheel bearing grease that's used for automotive use must not be used for this application Grease is what you need for Marine applications. Regular grease isn't rated to withstand being submerged in water, so it can't be used in this situation. Take a look at the bolts that hold the old brake assembly to the axle flange as you remove the old assembly It is advisable to replace the bolts and nuts with SAE Grade 5 bolts and nuts if the threads are worn out.

There is no problem. Added new information. When I bought all of them last time, they were all damaged The quality of the images this time is bad, though all looks good. There's no way to fix it.
