Brake pedal arm clevis pin (problem #2)
Turbo Mini Forums

I know this should be simple. I've rebuilt an entire car so this is irritating;

How the heck does the clevis pin that holds the brake pedal arm to the forked end of the 'linkage' of a servo come off? I've dumped the servo in favour of intercooler pipework (don't ask!) and have got myself (courtesy of MarkGTT) a new master cylinder.

I can see the 'offside' side of what looked like a clevis pin running through the arm/linkage. "Easy" I though "just feel round the other side for a split pin and job's done." No split pin, or any thing.

It being one of the most awkward areas of a Mini to 1) get your hand to, and therefore 2) nigh on impossible to look at without having chameleon-esqe eyes, I took a photo - and both sides of the [not-clevis] pin appear to be "heads" - how does this blighter come out?! I'm almost tempted to write my own solution;

"Hacksaw"

Many thanks, Dave.

depending on age of car ther is either an "E" clip or "R" clip preventing the pin from sliding out. Its a pig of a jobyou wiil have to get your head right into the foot well to get a look at it.

I assume you mean the pin that connects the pedal to the rod which runs up through the bulkhead?

If so, from my memory, this arm is fixed to the pedal with a rivet, not a pin so you wont be able to find a split pin! Assuming the actual pedal is the same when this is removed, the only way out would be to cut the rivet head off and drift it out.

having seen the other replies since writing this, possibly could be an 'e' clip ant one side of the fork.

The servo type brake pedal is different to the non servo type pedal.

The non-servo type pedal does have a removeable clevis pin, as the pedal attaches direct to the master cylinder fork.

The servo type pedal has a pushrod machine rivetted to it that cannot be removed, as you connect this pushrod to the servo linkage from under the bonnet.

I suspect you have been trying to remove this pushrod from a servo type pedal; in short forget it, you could get it out with a grinder if the pedal was removed, but the pedal would have in it the wrong size hole (too big) for the master cylinder.

You can swap over an earlier type brake pedal into your pedal box but you will find it will sit at a different angle to the clutch pedal. Best way is to get hold of an early type pedal box and fit it complete.

Argh. *Expletive*

Right. Pedal box exchange is clearly the "proper" way to go. Being an engineer I feel obliged to engineer a solution ("bodge").

Bush the pedal arm back to a master cylinder Ø hole, and clevis pin them together again.

Or depending on the amount of material around the master cylinder fork, open it out, but I'd be a bit cautious of this - failing brake components due to my own faffing about could be frowned upon by my insurance company/ policeman investigating me piling into a tree/ crown prosecutor, etc. Re-bush I think, unless I find a bargain pedal-box in the mean time (anyone?!)

Thanks for the advice folks, at least I know why I couldn't find a split pin!

Dave.

I would have thought someone will have a cheap pedal box for you
