Technical Becky's rear brake cylinders

The brake pipe corrosion on mine was not as bad as yours. Mine all looked ok but the flare nuts would not turn. Gentle heat was enough to soften the plastic. Metal underneath was OK. Too much heat would have done more harm than good.

Yours look beyond repair with all that bubbling. So removal is easy. :devil:

Braided lines costs are probably a bit more money but it's job done for good. Phone HEL to ask. No need for me to tell you what to do.

With braided on the back only, the brake pedal feel is the same as OEM. The pedal will feel hard only if you replace all hoses on the car. It's like a motorbike with no sponginess at start of travel. I now prefer the feel to standard on our other Panda.

Stopping effort is the same either way.

The aluminium corrodes just enough under the plastic sleeve to grip the nuts.



The raggy plastic can be peeled back for about 1". I coated the bare aluminium with some stiff copper paste. The usual CopaSlip (other brands are available :) ) is a bit too fluid but would do the job. The 1.2 has now done 2 winters like that and all is fine. The MOT tester is also happy.



sorry if this sounds picky but mine are plastic coated steel


and some copper grease causes a galvanic reaction between the copper and steel which speeds up the corrosion. Not all copper grease are created equal. Normal High temperature grease will do the job of keeping the water and oxygen out.

I'm sure mine were aluminium (classic white powder corrosion) but to be fair I have not tried a magnet. The copper paste I use is Action Can CS-90. Its high solids high temperature stuff but more importantly it's thick and smears evenly. Its done a good job on the bare metal brakes pipe ends.

I considered wrapping the bare metal ends with self-amalgamating tape but that would hide any trouble brewing so I kept it simple.
 
Thanks for this Panda Nut. I've turned up two suppliers in just a couple of minutes

I've been trying to make my mind up whether to completely strip Becky's rear axle out and send it off to be refurbished with a zinc spray finish (was it Dave McT who did this - looks like a good way to do it) or just do a rub down and repaint with the anti-corrosion paint I recently bought (painted the top spring plates with it) Then, when it later gets too corroded, replace it with one of these. At this price I don't think there's any contest. I'm going to do some researching into how likely this supply is likely to remain secure.

Hey, look, here's another one that seems to be in Denmark

PS - someone - was it you PB? bought one of these and seemed to think it was OK?

I am tempted to buy one and put it on the shelf at this price. I think Daffo's axles will be ok with TLC so an still thinking about it. I remember someone saying they are OK apart from a bracket being the wrong angle, this seemed to be to with the original pattern being slightly bent, but was easily overcome.

As any of you who've read my other posts will know my days "on the tools" to earn my living were in the late '60's into the mid '80's. To this day I still spend quite a bit of time maintaining and repairing family vehicles and helping out friends. As I have my own flaring tools I'm not against making up pipes for people - actually I really enjoy doing it - but it was only recently, working on "Becky", that I ran into aluminium brake pipes. Steel, copper, cupro nickel, even plastic coated steel, seen them all, but not Aluminium 'till now. Are aluminium brake pipes a uniquely Italian "thing" or are they quite common and I've just never run into them - or, more likely, just not noticed that the old pipes I was throwing away were actually aluminium?

magnet stick to mine 1.1 and 06

normal plastic coated steel
 
Maybe I was wrong. I've not stuck a magnet on my brakes pipes. I was simply going on the white powder corrosion.

As said earlier, on the 100HP I fitted a long HEL braided hose to each side which replaced two rubber flexibles and a length of metal pipe. The same could be done on the drum brakes.
 
Humble pie eating mode = ON
SORRY FOLKS THE PIPES ARE MAGNETIC :eek:
Mode = OFF

I was going by white bubbling corrosion under the plastic coating. Maybe they zinc plated under the plastic.
