Big Brake kit.

Concerning the lack of an aftermarket rear brake system - Buzz Overland makes a full ( front and rear ) big brake kit for the Grenadier. The e-brake is even hydraulic. You’ll find a few images of this within my build thread:

I like Buzz, have their drawer system. On the website it doesn't provide any info on the rear brakes, just a few photos.

Of course you aren’t typically drifting the Grenadier with the e-brake…

Challenge accepted!

Let me know if you have any questions.

Braking performance in our heavily loaded expedition tourer is substantially improved ( no surprise ) over the OEM front / rear braking setup.

It’s also easier to find front / rear pads for this setup - I’ve noted the relevant part numbers within my build thread.

Towing a ~6500lb trailer (with new good quality trailer brakes) from Ouray Colorado to Durango Colorado really changed my mind on the Grenadier's brakes (at least with the petrol engine and its poor engine braking). Despite me going much slower than the speed limit, not riding the brakes, keeping engine braking at ~5,000 rpm, and making sure the trailer brakes were carrying their share of the load, the brake fade was so bad that I had to take multiple breaks to let the brakes cool. The last time I pulled into a stop it took me about 200 meters to stop from 35 mph and most of that braking came from the trailer.

I have the Agile Big Brake Kit installed now but haven't actually towed with them yet. Around town though, they just feel so much more responsive. Better braking with faster response and better pedal feel.

The two piston front brakes and one piston rear are just not adequate for the towing loads the Grenadier is rated at. Sadly, it is only a matter of time until someone learns this the hard way.

EDIT - All that being said, I wish someone would create a brake kit for the rear axle that maintains use of the handbrake.

You know it’s bad when you have to take brake breaks.
I haven’t towed heavy loads but have noticed the diesel engine braking is great.
Also the ability to use low range on hard surfaces up to 80 kmh/50 mph is also great

I think I'm going to get the power brake system . I think anyone with a heavier vehicle or towing should consider a brake upgrade. Is was in very steep terrain today and it was a bit sketchy with the factory brake IMHO.

The factory brakes seem more than good enough until you really have to push that pedal, as in sh1t I've really got to hard brake - there doesn't seem to be any more stopping power however hard you push the pedal. Probably not describing it too well but if you need to make a close to emergency braking then the bite of the brakes does not seem to intensify. Yes it's a heavy old truck but I would expect some better performance when in brown trouser mode. I wouldn't go as far as saying brake fade but would certainly like a bit more feel and power.
