Oil immersed brakes rely on oil to cool them. Holding them on for ages without letting them off boils the oil off between the plates at which point no cooling is present and you either warp the discs or burn the braking surface off.

How old is the nh and is trailer on air brakes
Got 3 and find them all pretty much the same. 7050 left at 8k hours without them failing. Got a t7 200 on 6k hours. Brakes been fine. My tractor a t7 260 3k hours. No problems. T7 190 but it's just done around 700 hours.

We do go into the brakes at 5k hours though and check for wear and replace discs where required. This generally costs about 1k. I don't grudge this as brakes are a wearing part and it's much cheaper than them breaking up and putting filings through hydraulics. Plus lost time. Plan to keep them 10-12k hours so cheap insurance. Not sure if I'll bother doing brakes on 260 as it does no haulage. Just field work. Plus it's a autocommand so very rarely touch brake pedal.

Most trailers air brakes now. Got a fastrac that does bulk of roadwork. But if need several tractors hauling. Another tractor will go on a trailer.

I'm not sure about the operation of air trailer brakes on the newer mother regs NH but the older ones can be adjusted (certainly some can) to put the trailer brakes on with less pedal pressure (black knob you can reach from back window). Hydraulic trailer brakes on NH need quite a lot of pedal pressure to bring them in (too much imho) so you can't help but load the tractor brakes a lot. Its easy to look after NH brakes if you're towing air braked trailers with decent brakes but any linkage mounted implement of any significant weight is gonna kill them if driver isnt sympathetic.
It's ironic that we're on the verge of trailer brake testing and having to meet minimum standards yet tractors don't seem to particularly good brakes.

What would be the cost of fastrack brake service? I can't see why all tractors don't have external brakes to avoid the internal explosions

Think we've replaced one disc on fastrac due to dodgy seals on a caliper. I've got a demount sprayer for it, so often working in wet muddy tramlines. Which are hard on external brakes.

The pads and discs are cheap, and a farm mechanic can replace them.

It's not just the brake parts that cost the money,it's the collateral damage. Like I posted earlier, a friend had an estimate of about£15000 just because of brakes failing.

Depends how long you keep driving them after they've failed I think. We had brake failures on another brand of tractor. Just stop what your doing and put tractor on back of a low loader if you think they've gone. They were around 2k to do, but got caught early.

No someone who Did exactly that but the brakes ruining the oil also ruined the vario and oil pump

The new valtras have two seperate oils in the back end , I never studied it too hard but is the oil for the brakes part of the gearbox oil or the tipping pipes oil . It’s as if a tractor could do with 3 differant tanks of oil , 1 for transmission , 1 for brakes and 1 for tipping trailers, this way there would be no cross contamination. Now that valtra have split them up , which two are together.

That's always my bugbare with the Fendt trans. OK theres seperate oils which they make much noise about, but the brakes oil is still with the transmission, which is just the thing that needs protecting the most.
 
We’ve always had them...we’d also always had JD balers till last year...now I wouldn’t have one of you dropped it off and paid me a daily wage
I have a JD dealer five miles away and the only reason we haven't got one is because they didn't make a suitable size. The four cylinders weren't enough power and the sixes were too big. Valtra dealer is fifty miles away but the model suited better and love it,but there's no way I would ever tell someone to change from what they have always had unless they have a real reason.
