8770 brake reline

[Slowcow]

My 70 series brakes are making a funny noise, guess its time for new discs, current ones are about 4000hrs old.

Spoke to local dealer, he said 350 ish a disc, 2 a side 2 available

Anyone had wet discs relined? Was dear last time I did it £100 a disc!

Thanks

Is this not a funk backend or is it just a funk tranny mated to nh backend?

I have worked on ford tractors for over 40yrs and have never heard of these being relined, i have only seen two types sintered brass or carbon and would think it would be just as expensive even if it could be done, most times they wear out because of trailer work and bad brakes on the trailers unless the tractor is is being used in work where the headland brakes are used a lot , 4k on a tsa model is about the time they start getting problems from the carbon brakes.so i would have thought yours is not bad for one of these.....

 

[Slowcow]

Ah the jolly TSA, had one on a trailer, shed its brakes....

The 8770 only really does reverse drive work on the forager, there might be nothing wrong with them but I do recall the discs having a direction arrow on them (or am I going mad?) I wondered if that might cause early failure as only I drive it and am a fairly gentle sort!

 

[Slowcow]

Just to bump this, I've just pulled the bell housing off the left side and both friction disc are jiggered, the intermediate disc doesn't look very happy either.

I'm waiting for a call back from my friendly dealer but does anyone know where I can get pattern bits for one of these, the discs were 350 each last time I enquired and I can't see them getting cheaper

Your a star!

 

[Slowcow]

I've taken the plunge and ordered four discs.

Local nh dealer rang back and said there now £368 and have to come from yankie land.

The intermediate disc which is quite thick and machined however is 200 quid and they have UK stock?!?

Funny ol world!

 

[Slowcow]

They're here! And rather splendid too, good firm to deal with, said be with me on Monday and they came Friday

 

[Slowcow]

That's next Monday and this Friday

Het them into a bucket of oil for a day or 2 before fitting

What reverse drive forager do you use?

 

[Slowcow]

Good old sh40, on my second, second hand reverse drive one now, could do with another one

 

[devonboy]

you do realise that the other plates they bind onto will need polishing /skimming?

 

[Slowcow]

The piston and the retaining plate are very clean, the intermediate plate is going in the scrap bin, that's taken all the abuse.

I've not heard of skimming them as routine? If their nice and smooth I've always put it all back with new friction plates.

 

[devonboy]

you said your brakes was making a funny noise, which usually means damage to the piston plate. we would polish them as a matter of course as they ought to be like a mirror. We do have a local guy that can do it and its not expensive anyway so when we have it apart it gets done.

 

[Slowcow]

Thanks, the funny noise was the plates picking up on the intermediate disc, last time I had it apart it wasn't so bad just more wear next to the intermediate, don't know why they wear more there?

How much does he charge/where is he? I'll have another look at them in the morning but them pretty shiny, would need a wizard polish the middle one tho

 

[devonboy]

n. devon.would have to look up the price.

 

[devonboy]

80pounds ish per side

 

[Slowcow]

Just out of interest how smooth do the parts come back polished?

This is the new intermediate disc, it looks a cylinder after its been honed!

Pulled the right side at the weekend and I'm tempted just just put it all back in, 0.5mm wear on the friction plates, I will put the new ones in keep it all even!

Strange that one side is bu#$erd and the others fine, only time I split the peddles is to bleed it! I believe the master cylinders are supposed to equalize she both brakes are pressed too?
