Air Disc Brakes

I have trailer with disk brakes (EBS, RSS and all modern stuff)

Yep, more expencive to repare and maintane, but safety level is the different, truck stops like a car

 

I only have them on my trailers now and for about 5 months so I can't say anything to reliablity yet but they do a much better job braking then a drum brake. That is the way I see it, yes I am paying a bit more but if i stop 10 feet shorter that is one less car that I am going to hit. Also because of the design of a disc brake they provide better braking over extended periods because the disc will head up an expand causing it to touch the calipers more were as with a drum brake will expand away from the brake shoe and you will lose braking power.

I know someone with two tri-drive dumps with quad wagons that runs through the mountains, they have been in service for about a year and a half now and he has had no issues with the disc brakes yet (I know there are disc brakes on the truck and pretty sure they are on the trailer as well).

 

disk brakes are worn usually on rought roads.

One more important thing - do preventive repare. every spring I use to remove caliper, lubricate screw pistons and change small rubber boots if worn. Caliper maker (Knorr bremse, ore Bendix in NA) do not sell boots, but there are many aftermarke parts are available on UK sites I use to purchase on

 

That's a combination of EBS. And discs, the discs provide the stopping power and the EBS prevents locking up or jackknifing , as you can see 40 tonnes ( 90,000lbs approx ) stopping as fast as a car on a wet road completely controlled, basically EBS is ABS except it works for every wheel separately so you dont get that pulsing effect you get from ABS. These things could still be a little more expensive in NA but can you put a price a life including your own?

I'm now driving a Pete 387 and I miss those brakes, takes a while to get used to the brakes here

 

The Volvo Emergency Brakingsystem works very good ,this is a good safetythink to have this in every Truck

 

That's available on Mercedes for a couple of years now

 

Are the rotors on trucks slotted or vented in any way?

 

Ahh vented through the middle ; http://www.winnard.co.uk/images/Product_Images/Disc_low.jpg

 

Usually ventilated disls are used
