Brake master cylinder

[dapinky]

I have been half following this thread for a while, but not in detail ('cos i don't need one!).

But, am I ight in thinking the following MAY apply? :-

1) Lotus charge too much (as usual).
2) There is a cross-ref, but they're not cheap either.

and, hopefully,

3) There is a cheap alternative which will physically fit, but may not be a direct swap due to threading of the ports.

If 3) applies, am i right in thinking that such a cylinder would only need to have new brake pipes fabricated in order to do a good job?

If that is the case, then i will be interested - I've got plenty of brake pipe, line fittings and a good flaring tool!!!!!

Monty, I think the part numbers from the golden gate Lotus site were taken from the first post I put up here at the start of this thread. I'm now worried that the threads on some of the ports are wrong even though its otherwise the same.

In short those numbers may NOT offer an easy bolt on solution.... If you can confirm the original master cylinder has 2xM10 & 2xM12 fittings then they are probably ok, if not then its back to the Vauxhall/Lucas parts

I don`t know what the stock fittings are so can`t confirm if the stock pipe will fit.

But it`ll should still be worth buying one and if the pipe fittings are different then it`s possible to swap the piston with the new seals

BTW, i`ve done a search on the Un-part that Surfer has fitted but i`ve come up with a blank on that one

Surferphil,
I am in need of a new MC. Any chance you could let me know where you got yours from please?

The company is called 'Unipart' they are a large national company with trade counters all over, usually on industrial estates. Have a search for them on the web and give them a call with the part number on my post.

Cheers,

I tried the local Unipart (and other companies) but they couldn't match it. Their part numbers weren't in that format apparently Finally found a motor factors that say they will have the part with me tomorrow. Fingers crossed...

The important bit is the PMH392 as it's common to the Lucas part.

It's also important to find someone to order it from; who isn't retarded and can read his employers product codes!

[paza1]

Totally agree Phil.
Thanks for all the info guys
Just off to get the part...will let you know what happens
Cheers

Monty (or anyone else),
Could you post the number stamped on the bottom of the cylinder please? Mine appears to be 3 88F 3832 and 22 but I am not 100%.
Cheers

[Monty]

Mine is

2383 FBB 2
22

Bore size is 22.2mm

[paza1]

Same as mine then

Thanks for looking

Part No. LM50087 is not the correct item. The cross reference to PMH392 is incorrect. LM50087 is a 2 port version and we need a 4 port (as per PMH392).

Well those numbers do match up with my finds and Pete has one fitted Sounds like your guy needs more training lol

I was shocked by the price & non-availability of the cylinder.
Kind people at SAF (sutton in ashfield) found one for me.
Ref was LM50087 but it's steel not alloy but I can't see that will matter, just Colin's adding lightness.

Done a quick search on some of the part number above, didn't come up with much except this Italian site www.lpr.it/idraulicalpr.asp?lpr=1318

I wonder if it was just a case of incorrect packaging then because the sealed box had LM50087 on it So naffed off, I didn't check the MC for more numbers

The Delphi one that Dave posted up previously looks like a four port as well.

It's also important to find someone to order it from; who isn't retarded and can read his employers product codes!

I agree. I have tried 3 different Partco's and none of them recognised the product/part number.. in the end I called the Bristol branch who remembered your order... unfortunately I have to drive and get the thing because they wouldn't take my card details over the phone.. fair play I guess! I'm also going to abuse my sisters Unipart discount - 25% I think

If I still lived there I'd go and get one for you. There was someone near by with a pink m100 but I don't think they are on this forum. I think all the other Bollecs live the other side of the city and out in the country.
Ailwyn bought a BMC and fitted it recently, you could send him a PM to see where he got it from.

I just went to my local motor factor and gave them the Lucas number... this is why I can't understand why people are having so much difficulty
