|
|
I have just stripped my Morris 8 brakes and whilst putting them back together I noticed the adjusting cams do not align with the shoes. If the shoes were wider they would run off the side of the drum. Apart from welding a small plate to the shoes to contact the cam has any body come across this and any answers? |

Are the cams original?
If so maybe the shoes are wrong _________________ ROVER

Thanks for such a quick reply.
The problem is the cams have not been tampered with and sit where they would have in 1936 and the brake shoes fit the drums just fine. I need to com with someone who has rebuilt Morris 8 brakes. Maybe the adjusters never worked on that model, after all it was one of the first cars with hydraulic brakes.
OK got the image thing working so I posted 2. |

Great looking car and garage! Not sure about the modern bikes on the wall, I think you need a few older ones?
Uk was telling me at the weekend he has loads of brake bits, maybe for the later car, but he may be able to help you. I know you say the shoes look right to the drums, but are they right, they could have changed over the production years, similar size but different design. Just an idea?
Cheers

From that picture it looks like the wrong shoes, the pin appears to be in the wrong position _________________ ROVER

Hi, on the series E (which I know has the same linings but not sure if the shoes are the same) there are 2 adjusters per drum, with a steel snail cam that acts on the individual shoes. I'll check when I get home if they are the same and let you know.
Failing that give Eddie a call at Wyvern Spares in Oswestry, he will have all the bits and the knowledge! (he is the guy who has had the slave cylinders and coutless other pre war Morris bits re-made).
Cheers Dave |

good bit of detective work there by 47p2----i might suggest that the shoes are assembled upside down,placement of top shoe an opposing one will have the lug in contact with snail cam----thus adjustment can be operated via the backplate nut.

Thanks to everyone that helped. I fell out of the stupid tree and hit every branch on the way down. If I had looked at the photos I took of it coming apart I may have twigged it. The pins are in the wrong place because I thought they were for the hand brake mech. Damned cunning sorts at morris used them for the cams as well, so the shoes are on backwards. ( must have been a woman that designed that bit). And here is a photo of the rear shoes.
Regards Nic
PS I am off to the garage now. I also have a 1936 utility bike, a '60s Madison Revell, a 1974 Pashley tourmaster tandem and a 1978ish Holdsworth tourer. They are in the bike shed. |

Nice to see you`ve overcome the problem nic----falling out of the tree has definately reproportioned the brain cells--ha--ha.
Memory recalls a similar problem i had with twin piston type brake cylinders---trying to correct pedal excessive movement.
A holiday maker came in one day and asked me to adjust his brakes.In conversation,he told me the brake system was completely overhauled but the mech could`nt get a decent pedal.Took me a while to find the problem . locating springs that are put between the pistons were left out for some reason,so the pistons allowed themselves to return into the cylinder !!-----memories --memories.
cheers---Ray the Rocker.... |

Glad you managed to get the brakes sorted.........
An easy mistake to make, and sometimes it helps if others have a look and see what you dont. _________________ ROVER
