Brake servo which one

Post by backpain » Sun Jan 14, 2018 7:43 pm

I have a few parts to put back on the coupe after a part restoration ,
This servo being one its not been used for years so requires a overhaul by me a seal kit and band about £100 to get it done for me £250.
On Ebay lots of servo s for less than £100 the type that mgbhive sell.
So was just wondering what you guys would go for


I could do it myself but always the chance I could cock it up,,,big price difference as well ...cheers

I fitted a Lockheed servo to my Coupe - been no trouble but I did have to take one of the piston seals out to stop it binding on - well known problem and documented on the site.

Be careful when buying a Lockheed servo online. Many of the cheaper ones i.e. around £80-100 are described as Lockheed "type" or "style" meaning they're not Genuine Lockheed, but cheap Chinese copies. Be prepared to spend about twice that for the genuine article. Not saying the cheaper ones won't work or will fail in some way, just be aware.
( probable that even the genuine ones are made in China these days :roll: :lol: )

Mine has an SS1 servo - but I have a cable clutch.
It's really not critical, especially on a Coupé which wouldn't actually need a servo if it had better master/slave gearing :wink:

It's worth remembering that there are various servo ratios, even though they all look the same. IIRC the Coupe has a servo ratio of 2.3:1.

As Chris says, the Coupe brakes are very effective so don't get carried away and fit a servo with a 3:1 ratio as all you'll be doing are emergency stops! :)

I have a list of servo ratios somewhere so I'll see if I can find it.

If you have the Girling part number or someone can remember what else uses the same servo ( I cannot for the moment ) you can pick the one you need from this list.

Backpain, I plunged for the repair kit, though have not yet rebuilt my original fitment servo. I actually have two servo's though the original is damaged and beyond reasonable repair. But it's helpful to dismantle it and understand where all the bits go, so I can tackle the better one with confidence.

I'll declare up-front I'm coming at this from a competition bias. However, I never liked the brake pedal feel with a remote servo. My preference was to put the servo in the bin and press the brake pedal harder. The pedal feel is much better without them. Correct selection of a bigger master cylinder and changing the pedal ratio (moving the m/c cylinder hole on the pedal); I can't advise on the coupe, as I've never done the mod on a coupe, but it was pretty easy on my SE5 & Truimph Spitfire.

I thought that it was illegal to remove a servo when one was fitted originally - I might have misheard the law though.

It should be there if fitted originally for the MoT and being classed as a safety-related modification, there might be other instances where it could be an issue (Insurance, if not informed) but I'm not sure if that's so much of an issue as there is a note regarding "modifications for a specific reason, such as Motorsport" (excuse my paraphrasing), I think?
