Brake Servicing

[FC0058]

Hi All
I have almost completed my pre-nationals brake service and let me tell you it was well over due. No use having brakes is half are seized. Well I ended up giving them the full clean and flush. My problam now is that when I fit the the passager rear wheel it becomes quite hard to rotate. I have removed the wheel and it rotates fine and the drum comes off relatively easy.

Has anyone got any ideas as to why this only happens when I fit the wheel ?

Cheers Jim

Hi Jim, Is the wheel rim the correct one?

Hi Ace
The rim's are standard FE/FC, nothing has changed except the brake shoes and they are exactly the same as the ones I took off except a lot more pad.

Any grinding noises after tightening and trying to turn the wheel?
If there is grinding, pull the drum off to see what is grinding.
What happens if you tighten the nuts on the drum without the wheel on?

Sounds like the drum has a slight warp where the stud holes are. Without the wheel on the drum works OK, then with the wheel tightened, the drum distorts slightly and grabs on the brakes. This can be caused if the drum was difficult to remove and you had to pry it off with a screwdriver or the like. Fairly common occurence, but can be tricky to fix. You may need to get another drum.

It would seem that my front and rear drums are different. The difference is the depth. The deeper drums were fitted to the rear of the car and what seems to be standard drums were fitted to the front.

Any ideas, as I have swapped them and every thing seems to be OK ?

Jim, I seem to remember that some later model (EH?) commercials had deeper drums n wider linings; sometimes called "taxi" brakes... maybe this is where yours came from?
Someone with far better knowledge than me may be able to shed some light on this one.
(I have these brakes on rear - disc front)
Ken would know for sure...

FB and later drums are about quarter-inch wider than FE-FC (as are the brake shoes). Maybe someone fitted an FB/EK/EJ/EH rear end drum to drum on it? If it's FB or EK you'd be hard-pressed to even tell from the outside. The housings do have different part numbers:

FE-FC: 7408974
FB-EK: 7403421

I had a look a the diff and as RET said I could not find the part No, so did some measuring. Lucky for me I have a spare sitting out the back (No brakes fitted). The measurements were tha same. Fitted new standard brake shoes and standard drums. Its a snugg fit but it all works.

Larger drums are now fitted to the front and they fit well, must have FB-EK front end fitted. The car is fitted with a brake booster.

FB-EK front end can be distinguished from FE-FC by the different mounting of the shock absorber at the lower A-arm.
