How do I fit new brake shoes from Knott?

Lubricate all moving parts with copper paste or the like.

Which tools do I need to change brake shoes on Knott brakes?

To change brake shoes on Knott brakes you need basic hand tools — screwdrivers, pliers and spanners in suitable sizes. You also need copper paste, or an equivalent lubricant, to grease all the moving parts. We recommend keeping a brake adjusting tool to hand so you can adjust the brakes correctly afterwards. A good tip is to photograph the brake system before you take it apart, to make reassembly easier.

How often should trailer brake shoes be replaced?

Trailer brake shoes should be checked regularly and replaced when the lining is worn down. How fast they wear depends on how much you use the trailer and in what conditions. We recommend checking the shoes once a year. If you notice the braking getting weaker, or hear unusual noises when braking, it is time to inspect them and possibly replace them. Knott brake shoes are available in our range in several sizes.

What is the difference between brake shoes 200×50 and 160×35?

The difference lies in size and braking capacity. The figures give the diameter of the brake drum (200 or 160 mm) and the width of the brake shoes (50 or 35 mm). Larger shoes give more braking capacity and are used on trailers with a higher gross weight. We offer both standard sets and super kits for both sizes; the super kits contain additional components for a complete overhaul of the brake system.

What is in a Knott super kit for brake shoes?

A Knott super kit contains everything you need for a complete overhaul of the brake system. As well as new brake shoes it includes springs, bushes, locking clips and other small parts that may need replacing. The super kit is a practical choice when you want to be sure every wearing part is replaced at the same time. We have super kits for several brake sizes, including 200×50, 160×35 and 250×40.

Can I fit Knott brake shoes myself?

With the right tools and some technical knowledge, Knott brake shoes can be fitted at home — but if you are unsure we always recommend having the work done by a qualified workshop. It is important to follow the fitting instructions carefully, grease all moving parts with copper paste, and make sure the brake system is adjusted correctly after installation.

Which brake shoes fit my Knott brake?

If you still cannot find the right parts, check the diameter of the brake drum and the width of the brake shoes. We offer brake shoes in several sizes: 160×35, 200×30, 200×50, 203×40 and 250×40. If you are unsure, contact us with the details of your trailer and we will help you find the right spare parts.

What does "early type" mean on some Knott brake shoes?

"Early type" refers to older models of Knott brake that had a slightly different construction. These brake shoes have the same dimensions (160×35) but differ in their mounting points and design. If your trailer was built before a certain period, brake shoes for the early type may be the ones you need. We keep them in stock so we can supply the right parts for older trailers too.

How do I adjust the brakes after changing the brake shoes?

After fitting new brake shoes the brake system needs adjusting to work properly. The brakes should be adjusted at least once a year, and it is especially important after a shoe change. To adjust, tighten the bolt for brake adjustment until the brake drum is held fast and cannot turn, then loosen the bolt until the drum turns freely again. This gives the correct brake clearance and even braking.

We recommend always replacing both brake shoes on the same wheel at the same time, and for best results on both wheels on the same axle. The brake cables should be replaced at the same time to guarantee correct function and safety. If you are unsure how to carry out the adjustment, we recommend having the work done by a qualified workshop.

Why should I use copper paste when fitting brake shoes?

Copper paste is used to lubricate all the moving parts of the brake system and to prevent corrosion and seizing. The paste withstands high temperatures and makes sure the brake shoes can move freely in their mountings. We recommend applying copper paste to all contact surfaces between the brake shoes and the anchor plate, and to the spring mountings and adjusting mechanisms. This extends the life of the brake system and makes future servicing easier.
