Hi

I'm really lost with the brakes pulling on my series III 88 . the brakes are the two cylinder type.
With dual vacuum assisted master cylinder last year I had the same problem of pulling to one side , I fitted new shoes, and cylinders to the front and back , replaced various pipes just in case , but couldn't figure it out . I managed to get through the MOT because they let me adjust the brakes there on the test and it manged not to pull while on the rolling road but soon after again started pulling to one side.:confused:
There is no obvious reason for the pulling. I have just tried backing the adjustment off completely on both front wheels as the shoes where all new last year they should be about the same distance from the drum , but still the vehicle is pulling to the left.:doh:

I have checked the other possible causes , tyre pressure , broken springs , steering joints.

Anyone can sort this out and your totally my hero !

be 100% brakes are bled out
are brakes grabbing -sham fur edges
as series says on others
 
have you looked at the cylinders just to make sure they are not leaking, even good makes can leak after 6 months i should know, or try swapping the drums over.

:doh:Hi Thanks for the replies.

theres no grabbing the shoes are chamfered no fluid or grease on the shoes. and they are bedded in .

I have bled up pretty well , and even back bled under pressure on the right side, where the problem should be as its pulling to the left.

I have an feeling the master cylinder is leaking internally as I can feel it give under foot if I hold the brakes on and need a bit of pumping.

But this should'nt cause it to pull , should it ? any "play " air etc in the hydraulics should be even on each side ? :confused:
 
my master cylinder started leakin.......the only reason i knew was that the brake pedl got wet ! and of course the brakes were ****e !
 
I worked had a series that was pulling to the right HARD,

turned out the front left brake pads where a bit greasy and the front right drum was BADLY scored

replaced the drum, and cleaned off all the oil/grease and its pulling really evenly and well now

so check your brake drums as well
 
Drums aren't badly scared and theres no grease etc.
Maybe I'll try swapping the shoes , but only because I'm run out of ideas and can't think what else to do

when i said the shoes where greasy it wasn't quite like that, basically there was some dust sort of "stuck" to the pad, on the part that rubs

I am a bit of a newbie mechanically so if thsi is a bad idea correct me, but you could try switching the front drums from left to right and see if it still pulls the same way (process of elimination)

if that makes no difference try switching the pads around a bit and see what happens.
 
sounds like the problem i had on my old 2A years ago the drums are not 100% true and 1 grabs before the other
get them skimmed in an engineering works ;)
 
I have new last year original cylinders.
the shoes may not be all the same brand and new last year.

I may start swapping stuff around though not convinced it will help. also though not badly scored there are some shallow grooves on the drums and the shoes bed into their particular drum .

Ok ,so this is what I did this morning .

Made sure I had good hydraulic pressure to drivers side front ( right side of vehicle )
Adjusted front brakes and tried again - result - pulling left.
Adjusted left side back so , totally off - would expect then that it pulls to the right but... still pulls left !

Swapped the front drums , this helped , but still a tendency to pull left !

I think I'll have a look at the back brakes , just incase I guess if there was no braking on the right hand back brake then it would cause pulling left ?

from what i know if its pulling a lot then its probably the front brakes.
as they do around 75% of the work (or so I heard)

having mismatched brake shoes can't help

maybe try swapping the rear drums over to give yourself peace of mind (and check for oily shoes and scored drums while you are at it

sorry for the double post, but this is EXACTLY what our series 3 109 did, only pulling right

(this was with a new master cylinder that was pressure bled)

eventually I used some stuff (solvent type stuff designed for the purpose) to clean the brake shoes, and switched the drums for good measure, and after that it was perfect
 
Hi Thanks for your postings everyone . Heres were I am with It .

I checked the back brakes and all seems fine there , cleaned them up bled the right hand side ( as pulling to the left ) adjusted back up carefully.

Still have the front drums swapped over took it for a run and it is better but still a tendency to pull to the left.

What am I left with to try ?
I could swap the shoes, then both drums and shoes will be moved from left to right . if the problem is with drums and or shoes then the pull should move from left to right .... right ?

If not , if it still pulls left then the problem is not shoes or drums but further back, but the cylinders are good and hydroulics are good .

The only thing I can possibly think of is that the front right adjuster is slipping so I'm nearly straight away losing adjustment on the right making it pull to the left . umm doesn't seem so likely !:confused:
But somthings causing this so I'll check that tomorrow.

yea try switching some pads around, it cant hurt and if it starts pulling in a different direction then at least you know what the problem is
 
Hi:)

So some change I've managed to make it pull to the other side !

This was after swapping the shoes from left wheel to right .

So an obvious assumption is that its slippy shoes , but all four of the shoes look Ok , and I'vedeglazed with sand paper each time
Could there be some invisible contamination making that set of shoes slippy ?:confused:

Perhaps I need to replace the shoes , or a good degreaser ?

Perhaps just to make sure its the shoes I can change one of each on each wheel , then each whee should have one bad one and it should stop in a straight line ?
