hi guys need some help, my rear axle seal on my vw trike started to leak so i replaced it, had oil on my brake shoes and drum so i cleaned this up with brake cleaner ( this is on my right side ) reasembled and adjusted it all up. now its pulling real bad to the left and locking up, its not safe to ride. what have i done wrong ?

You haven't touched the left side of the trike at all. Assuming that the right side brakes worked fine before you touched them then clearly its whatever you did there. Cleaning the shoes and inside the drum PROPPERLY (no residue left) won't cause the issue. So either the brakes aren't bled properly or You have adjusted the cable wrong. OR maybe somethings not put together right. -Im guessing the whole drum had to come off to get to the seal

you may have to replace the shoes once oil is on the lining they are usually stuffed

yeah I would go along with that, once oil has impregnated into the brake lining material you cant clean it out. New shoes are needed and you might aswell do both sides so you get even wear.

I tend to agree--except the OP seems to be indicating the brakes worked fine before he took them to bits.

brakes were working fine before they were taken to bits

you've either adjusted them wrong or put them together wrong ,did you mix up the leading and trailing shoes ?
atleast you have the untouched other side, so you can take the drum off,look at them and compare and see where you went wrong. Pays sometimes to take digital pictures before you pull to bits so you can refer back.
If all assembled correctly then sounds like an adjustment issue.

Ok so logic says its something you did. Adjustment,bleeding if Hydraulc or cleanliness. (residual oil from the cleanup missed)

You need to be certain you have reassembled them properly first. Sometimes you can show the brake shoes a bit of flame to release the oil and then more cleaning with brake cleaner. Then one toasted shoe on each side might even it up again. It seems odd that they weren't uneven before you did the oil seal though which points more towards an assembly problem.

sounds extreemly like assembled it wrong take both drums off and check on side you did not mess with what you seem to have done wrong .

Ok so how about you do the simplest check/test/adjust first. jack the back end up and spin the left then the right wheel.See if the rotational resistance feels equal. If not then adjust the right side brake adjustor till it feels equal. Then take the trike for a VERY slow ride 100m or so and see if it feels better. if it does then great. If not then you need to look further.

mmmm reality is here a single lipped wheel cylnder seal that (Ya don't say if you removed the shoes to clean em) has had a bit of a wiggle jiggle and NOT been bled. means air in brake-brakey no workie.

Intrade/snoopy --ya may be right but why not try the simple stuff first?

If the shoes have been removed have they been put back the correct way round, by that I mean are they leading and trailing?

pulling left right not working once oil is on the shoes or pads its replacement time or ride slow and use brake off n on it may burn off the oil

shoes were not removed for cleaning i cleaned them in place. also just been told mechanic stripped left side as well as it had a siezed brake adjuster

crikey--then Im still guessing adjustment as first port of call

MMMKAY DAT'D BE DA SIDE DATS GOT DA SHOES ON DA WRONG FEET Leading trailing reversed and yip it'll pull dat way [rekon ya meknik-needs ta learn a bit]

Simple english version relating to leading/trailing. Viewed from the top. the shoe in the forward direction of rotation is leading. AND. fr- om the top rotational the lining has a gap. I.E. Top 12.0clock leading shoe lining starts roughly at 2 pm and trailing shoe starts at 11 am Kapeesh?

L O L. But Cuzz U noe da effective braking force on a self energizing leading shoe when the lining is an extra inch closer to the activator. (Or. the lack of an extra inch-LOL)

Yep, Rollers had 2 trailing shoes for smoother braking!

Its probably still got oil soaked into the lining that needs smoking out. Bit of a flame kissing needed.
