Clutch master cylinder push rod length
#1 Clutch master cylinder push rod length
hi All
Just wondering is the master cylinder push rod meant to be cut down ?
If I fit the new one I think the pedal will be very high ?
Also is this spring meant to go with it ?
Thank you all in advance

I should add that I cut down the one that’s on there to match the one before ( I know that does necessarily mean it was correct ) and it did not have a spring on before.
But the master cylinder seems to have failed again after less than a year ,and not returning very quickly was one of the symptoms.
Thanks again

Hi Grant
Mine is much closer to the length of the old one.
The spring looks like the one that sits within the pedal box to aid with pedal return.
Here are a couple of pictures that may help. Sorry they are such a mess - they are the ‘before’ pictures.
Cheers

Hi Ash
That makes more sense now I have seen your spring ,
I'm gutted as mine is there but offering no resistance at all so I guess it's broken , obviously being upside down in the footwell is a very uncomfortable clostrophobic place to be ,
I presume
A )there should be some pressure on the pedal even though the master cylinder is not connected and
B)
You have to remove the whole brake and clutch pedal box to replace it ?

You shouldn't "cut down" the pushrod but remove the boot and circlip underneath so you can release the pushrod and swap the original pushrod over to your new master cylinder.
You can buy just the pushrod from SNG Barrett for around £20 iirc and fit it to your new master cylinder if you want to be sure on length.

Hi John
Do they do different lengths then ?
As you can see it already has a push rod on it , but you can only have it on the end otherwise the bit you have put through fouls the neck of the pedal ,
I hope that makes sense?
Thank you

Hi Grant
I think it would be a pretty difficult job to replace that spring without the pedal box on the bench.
Without any connection to master cylinders these internal springs will return the pedals back to their resting position.
If you need any other photos let me know - I have collated a lot over the last few months. What did we do before smartphones!
All the best.

Don’t forget you can fit an external spring as a temporary measure. (Carb return?)

Hi Ash and Angus ,
Well it’s been a long hard day but I’ve done it now , started off replacing the flexible clutch pipe hidden up under the carbs which was a pig to get to , and then had to take the pedal box off to fit the clutch return spring not the fun day of fitting my new Su carbs and 123 distributor that I had hoped for :-)
Still have to put the box back in and connect it all back up and bleed it all but I’m at work tomorrow so that will have to be tomorrow evening . ...
Thanks again for all your help everyone as you can see it’s my first time tackling most of this .
Regards
Grant

Hey, it wouldn’t be fun if it was easy.
But some satisfying achievements there Grant and every job you do you increase your knowledge of your car.
That’s what I love about working on mine. Every task gives me more knowledge, greater understanding and I can visualise how things go together and work.
Although I will never get anywhere near to the knowledge of one Mr Moss!
Good luck with the rest of it.
Cheers
Ash

#11 Re: Clutch master cylinder push rod length
Hi Ash
Yes that's the fun part ! Grrrr
I'm just fitting the new master cylinder but if I do not shorten the push rid it makes the clutch pedal really high ?
Any thought s anyone should I soften it as per the orignal ?
Has anyone else had to do this ?
Thanks
Grant

That’s a great call Steve!
Grant, do you have the spacer that sits between pedal box and clutch master cylinder.
Zoom in on my photo and you will see it.
