Thread: Engine Brakes

I would say no as long as you don't over rev the engine when using it to slow the vehicle. It has always struck me as odd that someone in the aftermarket has not designed exhaust brakes to fit to 4wd vehicles. I can see applications for them when towing heavy loads etc. They are available for F250 and Dodge ram diesels in the states but I've not seen anything locally available.

do it right and you dont hurt anything, infact you can save wear on some components... (brakes and clutches to start with)

get it wrong and well bad things happen.


you can get exhaust brakes fitted if you want them. I have a couple Im yet to fit to a td5 and a sIII2.25D

trucks use them to save on the problem of brake fade assosciated with drum brakes used on long descents with heavy loads.

No problems with using engine braking at all... In fact, it's what Land Rover teach you to do when off-road.

How could I

Thanks for your expertise, Ive always wondered

I've considered the addition of an exhaust brake for years because on the long steep decents the engine breaking tends to give way to the turbo and the old girl starts to gather speed alarmingly.
What do you mean by getting it wrong Dave???
Steve.

getting it wrong includes screwing the double declutch on the downshift. which shock loads everything.

down changing to early and then snapping the engine up over its designed over-run speed

being lazy on the down shift, screwing the rev match and taking it up on the clutch burning the clutch.

they are the main culprits.

Approx 5 years ago I sent away for and received a pamphlet from an outfit in the Cairns area that made a kit for 4WD's. He had one fitted to his Patrol and found it very good for the steep descent down from the Atherton Tablelands into Cairns.
He had an ad in one of the 4WD mags.

I still wonder if the extra pressure in the exhaust system would cause any problems with turbo seals and if the seals were in poor condition could hot exhaust gas enter the lubrication system and would it be an issue?
