Massey 6480 brake master cylinder leaking

[dannewhouse]

I was out power harrowing today and noticed the cab full of oil, it's coming from the left hand brake master cylinder through the rubber cover.

I have read that you need to replace pressure vessel or something aswell?
Where is best to buy all the parts and what's involved, Massey want £650 plus vat for the double master cylinder.

6480 t3 early one with Perkins engine.

Also best place to get a new exhaust, (90 bend and first part to top of engine)

The cylinder can be got else where but you will still part with over 500
Accumulator from mf will probably have a fancy thread or fitting.....
Spurious and a thread adaptor....

What is the accumulator that I've herd about and will it want one of them?

It’s under the cab right hand side. It evens out the pressure taking out shock loads.at least have it checked out if it’s failed and you don’t replace it the new brake cylinder won’t last long

2 accumulators on them, 1 on the brake circuit, 1 for the gearbox.

 

[dannewhouse]

Who will check these?
I have pressure gauges but front axle seems very hard aswell so might as well go through everything.

Dealers should have the gear or any hydraulic specialists worth a try. Sometimes they just need a top up but the rubber bladder inside can also have cracked and lost the gas

I’ve heard you should do accumulator aswel, last time I got one was 172 plus vat for accumulator for clutch circuit but it’s same for brakes I believe or is on a tier 2,

my old accumulator was full of oil, bladder fooked unscrew end and see

 

[dannewhouse]

Think I will get them all tested by independent unless I can test with my guages when I look up how to do it.

Tier 3

 

[dannewhouse]

These cylinders?

 

[Farmer_Joe]

Yes, mine are actually different style to that, and lower down and in line

I put 2 cylinders on my 74 before someone mentioned about the accumulator

Just ordered an accumulator for my brake circuit, farming parts have 10% off and free delivery, so £211 inc vat and delivery, pretty sure my last one was not much cheaper than that as the price i quoted here was plus vat and delivery,

and on second glance they may be same as yours?

ring em with your chassis number.

thats one i got

Are both of these accumulators not just T into same hydraulic circuit?

What pressure should they be set at?

 

[Farmer_Joe]

Just to edit there having to refund me cant post accumulators anymore ! Bellends why take payment !

think it different circuits but I could be mistaken mf told me one is for brakes other clutch there must be some none return or something?

To test your brake accumulator go on a safe field and travel along,knock into neutral and turn key off
You should have at least 3 or 4 presses of the brake pedal to have enough brake to stop you
If you have no brake the accumulator is flat

It is also used as an energy buffer, so your system is turned on and off less frequently. When using a diaphragm accumulator, the system pressure stays longer. Temperature range: -20 ° C to + 80 ° C.
