What is wrong with new brake parts?

ciderman · Jul 15, 2011

I dont know....
working til almost 8 tonight with mates land rover.
new shoes and drums yet:
the wheels wont adjust!
most are locked solid.

WHY?

Which landy?

ciderman · Jul 17, 2011

hi.
early S3 , 88" very simple , it is just we cannot get an adjust on them.
fully backed off wheels don't go round.

Trewey · Jul 17, 2011

have you chamfered the edges of the noo shoes?
are the drums oval, or badly grooved or with a rough edge?

RaggedJoe · Jul 17, 2011

Hi, have exactly the same problem. 1976 S III 109. New (Britpart) brake shoes on the front, adjusters wound right back, drums will not rotate once installed. Feels almost like shoes are too wide? threw the old ones away before I could compare :doh:. Looking forward to collective wisdom.

PS Drums in good condition.

wow i had the exact opposite problem with ****part, new shoes on and adjusted to the maximum and still a long way off touching :/

Thats your problem then blue box strikes again, just google ****part.

Before conclusions of Britpart are jumped to...were they Britpart parts?

If you take the drum off and turn the adjuster - is it doing the job intended or is there no movement?
Did you replace the whole set of shoes/drums? Which ones are playing up?
Have you had the cylinders off as well?
Are the shoe springs in order and correctly installed?
And I know this sounds daft...but swap the drums
I know this sounds daft...but try swapping drums over from one side of the other (i.e from front right to front left) - I know that might sound a little daft...but I had this issue once and I spent ages scratching my head and going round in circles...I (accidentally) swaped the drums over and it cured the problem!

How did you get the drums on if they are that tight that they are locked?????

However, if they locked up after initially trying the pedal then I suggest you adjust the stop nut on the brake master cylinder, the slightest bit out and it will not allow the brake system to depressurise and release the shoes

Just a thought - if the shoes are too wide they'll bind up when you fit the brake drum screws. If you can get the drums on then the diameter is OK - are they only binding when you tighten up the drum screw or fit the wheel? I had this happen to me when a wheel bearing wore badly reducing the distance between the drum and the backplate.

RaggedJoe · Jul 21, 2011

What you describe is exactly what happened. Got the drums on, rotating okay, then tightend the screws and the drums wont rotate. I think I might try swaping drums side for side, as suggested above, out of desperation.

All wheel cylinders are okay, replaced one that was not. I beleive the diameter of shoes is fine. Kicking myslef for throwing the old ones away so eagerly, but they were oil contaminanted so no use even as spares.
Springs are in order, adjusters backed out and seem to operate correctly.

Meantime if someone has correct measurment for width of shoes (front of 1976 109) that would be useful.

Still the same.............

Just fitted Mintex shoes to mine some suppliers now showing these available from Britpart.
Trailing shoe linings are glued on higher up then my previous set and had to chamfer top 1/4 " as reversing was not possible due to position of lining also chamfered lower edge of leading shoe so drum could not grab in reverse.
Not impressed so far as shoes are wearing in the centres [old shoes had very even wear] and brake efficiency is still not as good as old ones after 300miles

joe27979 · May 1, 2014

mine were locked until I fitted new bottom springs, its what stops the shoes falling against the drums...a good long chamfered edge will help also.

peter8315 · May 1, 2014

i had a very similar problem, found that i had fitted the top spring facing outward and this tends to pull the brake shoes off square so both springs must be on the inside of the shoes ( between the shoes and the backplate ) to hold them square to the drum,

That's what I'd say too .. Springs fitted wrongly, holding the shoes at an angle, not square to the braking surface of the drum ...hence gripping and holding.

Were edges chamfered

Blackburn · May 1, 2014

10" single cylinder only have one spring shoe to shoe ,top spring is from post to leading shoe inner pin.

ebbadger · May 1, 2014

as this post is 3 years old I would hope the op had sorted it

cheers steve

Had exact problem on my series, was the britpart parts. Had to grind the shoes down so they were narrower, OE shoes fitted spot on .
