Brakes

Post by **andyreeder** » Fri Aug 04, 2006 4:55 pm

Yes the dreaded brakes, when i put my foot on the peddle it stays down and the brakes stay on (slightley) i have to lift the peddle with my foot to fully release them. other than that the brakes work ok afer a pump. what is wrong ? Is it the master cyilinder ? or could it just be the peddle thet tight on the cross shaft that it pivets on ?

Or the return spring on the pedal or the release spring on a shoe - I'm guessing here

The m/c should return even if the pedal return spring is missing. Pulling the pedal up will not pull the m/c back anyway - the actuating rod pushes but deosn't pull.

First thing to check would be pedal shaft.
The m/c itself is 'unlikely' to stick (unless the seals are swollen) but from description I can't see how that would fit anyway.

Start by spraying the pedal crosshaft assy with release oil - and as Mr G says - check the return spring which has probably rusted away.

Thanks thats what i wanted to hear. I have checked the brake shoe spring and they are all ok. I have even bled all the brakes again. Ill try the cross shaft next.

Cheers i let ya know if that fixes it.

I think its the returne spring. It had come off so i reconected it ant it seemed ok untill i put the cover back on and the carpet back and it just was not strong enough to return the peddle again. So i have ordered a new spring. Hopfully that will cure it

. WHAT A FIDDLEY JOB. I found myself saying a few choice words, Blinking & bluming

you know the ones i mean.

Ill try the cross shaft next.

get the master cylinder floor plate off, oil the shaft from here and aslo from below where it passes into the chassis leg and gearbox. Work the clutch and brake pedals in opposite directions.

yes - it can be a fiddly job. I've found it easiest to put a loop of electrical wire around the near end of the spring and use that to stretch it,leaving the other hand free to 'try' and align it with the hole in the link pin.
[If the link pin is free to rotate, this job can be done in a few minutes!]

I have just fitted a new clutch shaft and new bushes on my brake pedal and
drilled an oil hole in the pedal while I had it out to facilitate maintenance.
Mine is a 1957 car but I believe the later models may already have an oil hole
