MF 50D BRAKES

[topkit]

Anyone on here got much experience of MF50D brakes on a 1985 Elite machine are they oil immersed or dry disc, what are they like to do and what sort of cost. Thanks

Got to be wet brakes. Assuming to be the same system as 200,300,500,600 and 4200 series MF tractors.Sorry,can't help with what's involved or costs.

I would perhaps ask a question or 2 on one of the farming forums. They are bound to be similar to the MF tractor of that time as Agrimax has said.

Search reveals they are both wet and dry brakes, which is confusing.

[For wet brakes, it seems the 50b and 50d used the same discs in wet brakes. ]


This site below suggests there are no 50d dry brakes

and gosh it's nice to actually find web sites doing what they're meant to do, so here's this site below. [In other words, a place that has stuff, with an idea of the price included, otherwise it's just some site that's advertising it could supply the parts, which is freaking pointless really in the opnline world.]

[boy that is one nice site, no signing in first, no having to phone to get an idea of prices, no mucking around, nice except the for the shoes, which maybe might be for a handbrake ... ]

P.S. It should be evident if you have a wet type, as one needs to service the fluid reservoir

Edit for extra links and info

I am surprised if dry brakes would have been used on an 80s machine.

I agree, I would tend to think they are definitely wet, it's just a few links blurred what the 50 d might do.

Manufacturers though, do sometimes venture down strange paths, if you'd said they'd moved to used brake fluid to push the brake piston, I would have said, "no way!!!," but alas they have according to the link above with the parts breakdown. Not having seen a modern Massey (yup they are indeed rare up my way) I would hope that the "brake fluid" wet brakes are external to the transmission case in the case of the piston seal failure, brake fluid not being a good thing to mix with other oils and generally detrimental to the typical coated surface.
