Scudo (Expert/Dispatch) Rear Shoe Auto Adjuster Questions?

[Mottie]

I have both types. Can’t get on with the hand pumped one and prefer the basic one. To get the filter out, pull the filter up a little, grip it with a pair of pliers and twist and pull. Be brutal.

In that case I will need a late Xmas present of a pair of thin, bent nose pliers. The resevoir is under the scuttle overhang, so not a lot of room to work above it.

Mum's cracked and leaking cistern - replaced. Van's leaking rear brakes - replaced.

Just noticed occasional small drips of diesel on ground and smell of diesel from van. Will no doubt be back for more advice.

Looks like the fuel filter housing is leaking - more of a weep than a regular drip. Seems to be from the rubber seal where the top is held down by a screw on ring. Not sure if these types of plastic housings on HDI Citroen, Peugeot, Fiat, etc engines are usually problematic. When filter has been replaced in past, has taken several attempts to stop the rubber seal leaking - worse than it is now.

Few years ago a garage changed the filter while it was in for other work. Straight after when I was driving it, it was leaking quite a bit. Took it back and mechanic thought he had stopped it. Had to go back a second time - mechanic emptied his bin out on the floor, found the old seal which he reinstalled and leak stopped. Each time the the filter has been changed since, the original seal has been reused without any problems.

Anyway, I have just ordered the proper tool (photo below). When it arrives, I will see if the securing ring needs a slight tighten. If this doesn't cure it, I will get a genuine filter with new seal and put that in.

Absolute nightmares to get to seal .

The tool should help but look around for new filter with housing complete ? Much easier and not usually badly priced.

Can't remember the site but try ' Alfa and fiat spares' online ?

Alfafiatparts.co.uk. nothing to do with me but often useful for filters and housings complete

Thanks, that confirms what I thought. Not a very good design. Do you usually find that cutting your losses and buying a new one solves the problem?

Genuine ones not too expensive on Ebay.

Yes. Easier, quicker and usually only a little difference in price.

A good smear of grease on the rubber seal often sorts it, newer ones have Torx screws I think.

Ive never usually been that lucky. The cases often seem to be just so slightly out of round after a few filter changes.

I never even fight them nowadays. A complete unit change or not at all.

Just wanted to check what makes the rear drums' adjusters turn to make the shoes move outwards to the correct gap from drum. Unless I have it wrong, some work by pressing the brake when going either forwards or in reverse - others when the handbrake is operated.

Looking at the picture below of the setup I have, the adjuster seems to be located one end in the shoe and also the handbrake lever. Because it is located in the handbrake lever, does this mean that operating the handbrake makes the adjuster work? Or does pushing on the footbrake make the adjuster work?

Supposedly, each time you engage your handbrake, if there’s enough movement, the lever should move the adjusting wheel. Rarely happens though.

 

[carmanmemoranda]

Every time you use the footbrake it stretches the adjuster bar out and allows it to click round if it's ready too.

The adjustment is NOT done by the handbrake. Using the handbrake without the adjuster spread out will just give you a long brake pedal and a long, ineffective handbrake travel

I finally got around to throwing the old brake components away today from when I replaced all the innards on the rear brakes. As I was doing so, I pulled the adjusters out from their locations between the old shoes. I had a play around with one of them to see how it works. I can confirm that the adjusters work by being compressed - ie. they get squeezed when the handbrake arm in the drum moves when applying handbrake and the sprung steel piece on the front clicks the wheel around slightly. Very similar to the adjuster in this excellent video.

In fact it's just as well I replaced everything. I didn't realise when I did the job, but one of the adjusters was actually broken and the threaded part fell out when I removed the adjuster from between the shoes. The spring bit on the rear of the adjuster was cracked in half and made the adjuster inoperative.

Re. the slight leak on fuel filter housing. I received the correct crescent-shaped Laser tool in the post to loosen/tighten the lid securing ring on these HDI housings. Have slightly tightened the securing ring without going mad and it did budge slightly. Will see if nipping it up slightly has stopped the drips. New filter is due now anyway, so I will more than likely take Carmen's advice and put a whole new housing on when I change it.

Easy way to check it.

Assemble the brakes, don't set the adjuster, then use the handbrake and see if it adjusts up

Then do the same and don't use the handbrake, just pump the foot pedal (listen to the ratchet clicking) and then use the handbrake.

See which way works, and which way doesnt
