Hi Thankyou for watching The length is the overall length from towball to back of the trailer.

Glad it was helpful!

Hi Thankyou for watching This can vary and needs doing based on distance and time if a trailer is used a handful of times a year and short distances it needs doing once or twice a year. if its used regular for short trips every month this would be the same for occasional long trips. for people that are intensively using such as car transporter companies that do 500 miles every day its recommended every week. We do have a recommended maintenance schedule on a website we had for information this was written in 2012 and staff from Knott and Bradley looked over this and agreed this can be viewed at. www.uk-trailer-parts.co.uk/trailer-servicing-maintenance-schedule/

Glad you think so!

This works on any stubborn bearing and will help if you don't have a press available.

It's unfortunate you didn't watch first but hopefully our videos will help you maintain your trailer.

Glad it was helpful!

No problem

This is a battery powered ratchet the one in the video was a snap-on but we now use Milwaukee

Hi Your trailer does not require reverse lights this only came in when trailers required approval in 2010

No problem 👍

Thankyou

Hi on European trailers / caravans with brakes since the mid to late 80's you are not supposed to have a safety chain. with experience forgetting to take an handbrake off on a caravan and testing brakes on trailers with a car I think it would slow quickly not come to an immediate stop. I do agree if people are not paying attention it could cause an accident but it will no out brake a car. This will only happen on a well serviced trailer. it does worry us how many trailers we see that would not stop at all if they came off.

Glad it helped

Glad I could help!

Hi Check the adjustment is all correct, when adjusting always turn the drum in the direction it would go as you travel forward. if you turn in the other direction this will activate the Auto reverse mechanism. check the reverse mechanism us operating correctly, and make sure all moving parts are operating freely including the brake cables. Hope this helps Towing and trailers ltd

@@TowingAndTrailersLtd yes I did that and now all good 🖐

Glad you like them!

This can be a bearing stuck on the shaft it may need a puller. I am not sure what you are saying about the expander but if this is open remove the brake cable and push the expander forward if its open through the brake cable hole.

Thank you and hope it helped

Hi The Loctite is blue on all Genuine Knott Adjusters the ones you have seen on line are probably copy / None genuine products. We only stock Genuine Equipment when it comes to brakes as over the years we have seen many problems with copy equipment. I have seen copy equipment brake drums and bend backplates so the slight saving you have can cost an axle. The loctite is to create some resistance not to lock the adjuster so the adjustment is just a little stiff. You should never adjust the brakes on the cables as this opens the expander. if the expander is open you have less travel for your brakes and the force as the force the cables apply is also at its maximum as the cable is pulling straight backwards rather than at an angle.

Hi Well spotted Unfortunately I re assembled with the brakes with the expander the wrong way round the expander should push the shoe that is on the reverse mechanism. The correct way is as it was at the start of the video. Sorry for the confusion.

Glad it helped We use a paraffin based solvent but in the early days we would use diesel but it was smelly many company's are using a water based cleaner. any thing will do than thins the grease to clean it out. Most auto spares shops will have some sort of degreaser like your no nonsense degreaser you mentioned. I would avoid brake cleaner as you will need a lot and it could get expensive but it would work.

Hi The over centre handbrake that is operated by a large spring (energy store) has been around since the 80's Bradley moved over to this fully in the 90's Knott moved over to it soon after but there were still couplings around with ratchet handbrakes (not usually used on new production trailers) until about 15 years ago. This video was filmed in 2019 and the al-ko coupling that is shown on the left seems to be disappearing now as when we order it we are getting couplings in some weights that have an over centre handbrake that is slightly different as the energy store ( spring) is mounted under the main body and does not stick out of the back. I think in the next year or 2 you will not see any couplings (new stock) available with a ratchet handbrake. there may be the odd new coupling left that has been sat on some ones shelf. Hope this helps Towing and trailers Ltd www.towingandtrailers.com

@@TowingAndTrailersLtd I have two trailers. One a small goods trailer (from Trailer Europe in Hungary) with a Knott coupling and the other a caravan with a late 1990s/early 2000s Al-Ko coupling. The former with an over-centre handbrake and the latter a ratchet style handbrake. Personally, I much prefer the over-centre style handbrake for ease of use and I tend to feel that the handbrake works better. Without changing the entire coupling, is it possible to switch to a Al-Ko over-centre handbrake?

Hi I don't Know why disk brakes are not widely used but I do understand that there are some developed. I understand but can't be sure that it is to do with the fact that brakes in Europe and the UK work on an overrun system then need to reverse automatically I have heard of a couple of ways that disk brakes have been manufactured but it has been too expensive to be adopted for mass use. due to this it has never taken off as larger numbers are required for production. Please note this is just rumours I have heard and may not be entirely true but I have not seen any information about disk brakes for over 10 years. Hope this helps

@@TowingAndTrailersLtd I’ve just realised that if disc brakes are not used outside over winter they will rust badly.. as do cars disc brakes if unused..

I like the click type but other people use them and I know that the digital ones will not be left with torque wound on them damaging mechanisms. I can also hand it to any one they don't need to be able to read a micrometre style gauge to set it a digital wrench. If I am doing something I often have people come to me asking Questions this can distract me and the counter that the digital wrenches have is handy to see where I have got to. The wrench I don't like is the one that flexes I specifically brought the one in the video to do the filming and once it was filmed I gave it away as I don't trust it for use in our workshop.

Hi I know that it is not a done practice to torque a wheel in the air. When I have serviced a trailer I always check the brakes and leave them locked in the auto reverse position. I then torque the wheels this gives me an Idea that the brakes are working well. The wheels then settle and are torqued when the trailer is collected by a customer as a final check. Thanks for watching Towing and trailers ltd www.towingandtrailers.com

@@TowingAndTrailersLtd It is also not a safe practice for you as that is a good way for something to fall from a lift or jack

I understand what you are saying if it is not securely supported We do make sure that trailers are secure while we work on them. The trailer in the video was on more than suitable axle stands. When a trailer is serviced with sealed bearings or a stub axle is fitted you are applying 280 - 850Nm to the same area on a trailer. If it is safe enough to tighten one of these it can manage a wheel stud / nut at 60 - 195 Nm Hope this helps Towing and trailer ltd www.towingandtrailers.com
