Disco Brake Reservoir

[p38arover]

Is it necessary remove the master cylinder on a Disco 1 (Non-ABS brakes) to replace the reservoir and seals? Our is leaking at the seals.

[Scouse]

No need to remove the master cylinder.
Tilt the reservoir towards the O/S & ease it out.

The manual mentions taking care not to damage the outlet ports but, knowing your luck Ron, I won't mention that.

You can buy the reservoir rubbers separate so it must be possible. When mine leaked I did the whole thing. Was not much more to get the whole kit from paddocks than just the reservoir rubbers locally. Plus I got a bunch of other stuff on the same order.

Imagine how annoyed you would be if you bought the reservoir rubbers and then broke the plastic pipes they feed on to :(

I did this about 8 years ago on mine. I got the rubbers from LRA. they were still expensive. Still working well.

Just a hint. Do not try to pressure bleed the system. I bought this U beaut pressure bleeder mainly for my BMW, but the lid fits the RRC. Pressurise and fluid goes everywhere from the reervoir rubbers.
So I use a Mightyvac.

The brakes shouldn't need bleeding if you're just doing reservoir seals (if you're lucky).

It was just a general thought, as I flush my fluid every 2 years. I have had a Mityvac for several years and recently got a pressure bleeder, but no go.
AFAIR I do not think I needed to bleed either, but it was a loooong time ago.

Bugger! I couldn't find the rubbers listed separately so I ordered a new reservoir kit (I haven't got it yet). The local LR specialist said you couldn't buy the seals separately.

They also told me this morning I need to remove the master cylinder as there is a drain tube into the front seal. Unless it is removed you can't fit the seals.

I'm now confused.

[Scouse]

I haven't done one, I'm just going by GTR.

The procedure in the manual has the master cylinder removed but there's no connection with having the M/C fitted or not fitted that I can see.


BTW, the reservoir is fitted the reverse of removal. Start at an angle & roll it in the master cylinder.

[Utemad]

Ron AFAIK there are two kits for the brake master cylinder (plus just getting the reservoir seals separately). One is the reservoir kit which comes with a new reservoir and seals for it. The other is the master cylinder kit which comes with everything to do the master cylinder (including the reservoir seals but not the actual reservoir).

If you remove the master cylinder and disassemble to make it easier to fit the seals you will break the part they warned you about anyway as you have to to get it apart.

So unless you have the full kit DO NOT disassemble the master cylinder.

I know MR in Redcliffe have the seals. They were either $40 each or $40 for the pair. Another place had them for the same price. Hence why I went for the full kit.

9. Grip outside of transfer housing with a suitable
pair of pliers, carefully pull, working pliers in a
backwards and forwards rocking motion to ease
housing off master cylinder. Discard housing and
vacuum seal.

That is where you brake the part. It is the first step of dismantling the unit.

[PhilipA]

If I recall, and I may not, I helped with a big screwdriver betwen the two drains.
They also mean "side to side" in relation to the master cylinder as you would grip it across.
I am assuming its the same as a Range Rover.
Just an idea . A pressure bleeder pumped up could only help with the process.

I did mine last month and I eased the seal into place with a small screwdriver being very careful not to puncture it. I did not remove the master cylinder and there was no need to bleed it,

Thanks gents. BMI sent a master cylinder kit STC2901 instead of a Reservoir kit STC2902.


My local guys found a couple of seals for me so I'll try just the seal route tomorrow. The little spigot on the thingy one is supposed to remove first looks somewhat vulnerable.

If I break it, it only means I wait until Monday for STC2902.

[Utemad]

Ron if they sent out a master cylinder kit then it should have the reservoir rubbers in there.
Also the spigot you mention that is vulnerable is not part of the reservoir. It is part of the transfer housing which will also be in the master cylinder kit.

Ahh, thanks Justin. I had better double check.

They looked (I didn't :( ) in the packet and said the seals weren't there. The yellow plastic housing was there. The master cylinder kit was also twice the price of a reservoir kit.

If needs be, I can go and get the STC2901 master cylinder kit tomorrow - it's only 5km away.

[p38arover]

Can I withdraw my thanks for this useless post! :mad:

:D:D

Don't forget my luck in getting the wrong parts late on Friday arvo when they are shut tomorrow.

[Utemad]

Ron I have been looking for a photo and just found one.

I looked at this photo before I ordered mine from paddocks to see what was included in the kit. Paddocks were not 100% sure if they were included.
The transfer housing is top left and the two rubbers in question are on its right.

[rovercare]

Just tug the resevoir off already and replace the seals, its not rocket science, just be careful;)

No need to bleed after either:)

The seals are stupidly dear, for what they are:mad:





And remember, hose the mess away afterwards:D

[langy]

Oh, Mr Beckett,.... remember to remove the nuts/washers under the reservoir involved before tugging the reservoir off. Thats why (As Mr Scouse said) you tilt it to the side to get if off.

[p38arover]

Thanks all. Sometimes you blokes are worth knowing! :D

I shall look at it tomorrow - after I replace the rear hub seal..... :(

But now, it's time for some kip - I've only had two hours since getting out of bed at 9.30pm yesterday.

Hmm, tomorrow I have to demonstrate the Honda CB350-Four cafe racer to some prospective buyers.

What nuts and washers, Mark?

I removed the reservoir, fitted new seals and reassembled it.

Getting the rear seal in was a bit of bother but done successfully. I even water blasted out the muck from the reservoir then flushed it clean with metho, a nice dry out with a hair dryer and it's a goer.

I'll see how it is tomorrow.


All this work for a car I'm selling! :(
