#1 Brake pedal travel..

Post by RobertGrieve » Sat Aug 11, 2018 12:00 pm

Hi everyone

I’m in to 50 miles of running in after a restoration and today have experienced odd behaviour with the brake pedal travel. From cold and during running the pedal is nice and high and firm, the car brakes evenly also. After returning home I then went to go out again, however I noticed the pedal travel had dramatically increased before any braking took place, I’d say an inch or so more.

All vacuum hoses are the correct type hoses, all new, new servo, vacuum tank, master cylinder, fluid topped up to full.

After having left the car for half an hour or so, all is back to normal... odd.

Anyone had something like this before?

Cheers, Robert

Yup.
It was air in the system. Took quite a few bleeds to clear it.

Hi Robert,

Also a similar experience to Chris. I ended up buying a vacuum bleed tool that you attach to the nipples (car) that sucks the fluid through to bleed the system rather than the type that pressurises the already fragile reservoirs.

Even then it took a few goes

This was a full new empty braking system.
All seems OK now even after standing and/or running.

Thanks both, I reckon in that case il get a vacuum bleeder and have another go, so far just done two bleeds the conventional way from the pedal with a non return bleed line!

Hi Robert.....i never have any trouble with this method even when filling an empty system..easier with two but you can do it on your own....starting at furthest away wheel....attach tube to nipple....one way valve is good if you have one..open nipple..press pedal down and hold down (piece of wood works ok)..close nipple...release pedal...then repeat....air cant get in via the nipple becaus its closed as you release the pedal...

You should bleed in the correct order
Nearside rear
Offside rear
Nearside front
Offside front
