Brake pedal adjustment

[GV]

A short while ago there was a thread on adjusting the brake pedal travel from inside the servo. Has anyone done this and if so how is it done and what was the difference after the adjustment was made.

Thanks guys

You have to remove the master cylinder of the servo, you will then see a rod sticking out of the servo, can't remember how to adjust it now, but if you do it to much the brakes eventually won't release.

I've done this recently

The adjustment is at the top of the pedal, inside the car.

You have to remove the master cylinder to see the actuating rod.
I discovered that over the years the actuating rod has worn away a bit which
has resulted in excessive pedal travel before anything happened. Combined
with a brake bleed it has improved my brakes quite a bit

As Blaine says - don't take all the play out of the mechanism

Isn't the adjustment at the end of the pushrod - where it joins onto the fork that swivels on the pedal upright?

What you do is undo the locknut, then you can screw the pushrod in or out with some mole grips or pliers, then re-tighten the locknut. Or am I thinking of the clutch pedal?

on my 82 280, it's the Cortina Mcyl and servo.

take the MCyl off the servo (2 nuts to undo), and you can adjust the 'cap' bolt on the end of the rod. There is a locknut to undo, and then the bolt will unscrew. If you do it too much, the MCyl won't be fully released,and brakes will lock or drag.

I adjusted mine out about 2-3mm, and it makes a bigger difference to the pedal feel/play than you might think, as its multiplied by the pedal (long short/lever etc). I did check carefully that brakes were OK afterwards...

I also discovered the clevis pin on mine was quite worn, a new one helped with play too. (the pin from pedal to servo rod) Worth a look....
