OH NOES!!! Brake pedal Freeplay adjustment NA

Ok, i have made a BOO BOO!

When i was struggling to remove the Pedal Box, in my FRUSTRATION, i actually at one point though i needed to remove the pushrod from the brake pedal to the master cylinder.

I now know this was not needed, and i never actually removed it.
What i stupidly did was just start unscrewing the whole rod before coming to my senses and realising that was the wrong thing to do.

After getting the pedal box back in the car i just twisted it a few times, was not even sure if it is threaded on not on the otherside.
The side where it connects to the master cylinder i presume.
Then returned the locking clip and finished the job.

It seemed to go back onto the pedal and i inserted the pin.

Cut to a few days later, i finally get a chance to go for a quick drive to try and get this Locking wheel nut removed.
Seems fine, though i do notice the brakes feeling stiffer. Almost as if i had braided lines.
After a very short time, and a few brakes the pedal goes rock hard and i can tell the brakes are actually clamping down.

Let it all cool down, and get the car back home.

I now realise, after a quick search that the BRAKE PEDAL FREE PLAY is CRUCIAL!!!
What i think i have done is lost all freeplay, which allows no space for the transfer port to do its job and allow the fluid to return.
After a few braking moments the fluid heats up making it even worse.


Is there a way to reset this Freeplay from home so it is correct or is this going to cost me BIG BUCKS? :oops: :oops:

Feel like such a Dick. I do not usually make those kind of mistakes.

I need to get this right for when i install the new brakes and rotors i have coming.
Do not want to ruin them obviously.

Easy fix. Page 04-11-03 of the factory manual "Brake Pedal Adjustment".

Ok, finally got a chance to give this a go.

I loosened one nut but the other nut that actually allows you to turn the pushrod is welded to the little bracket that attaches to the pedal.
How do i turn the pushrod?

Can anyone please help me?
In all the Manuals i have been through, they all just say loosend D and turn pushrod C.

Clearly i am doing something wrong. :cry:

The threaded rod goes through the welded nut.
You should be able to turn the rod with just your fingers after loosening the lock nut.
Spray some WD40 onto it, wait a while and give it a go.
If you still can't move it try rotating the rod with some long nose pliers on the unthreaded portion of the rod.
