Cleaning steel brake pipes or tubes inside... how??

[Bob McNeill]

Try cleaning the pipe using bowden cable, old pushbike brake cable, feed it in spin it in the drill, use it like a rifle pull thru. New pipe is safest.

Although I am not in a rust prone area, I intend to replace all brake pipe.
I just bought 2x 7 metre rolls of 1/4 'bundy' pipe & a couple of handfulls of flare nuts for around $190. This way I know it will be right!

Hi Ian - don't waste time and effort trying to restore those. Go new with either a brake shop or get Howard to make you a set.

Well:

Here are the pipes and as you can all now see the rear main and front chassis rail/ frame tubes are cactus.

Petrol cleans all the grease off them, but you have to be careful not to get it inside the tubes as it reacts with brake fluid... mind you the score is 1-3 with one pipe salvageable.

As you can see the rear main pipe was extremely pitted, and I managed to snap it on removal. It was good experience, as I was unsure if the pipes were pre-bent. It appears that by & large they are not except for a few tight radius's.

Having a 7/16 flare nut spanner will allow me to get the remaining unions undone. I feel like I am going backwards in destruct-a-tation, not forwards in restoration.

Howard; Fancy a weekend at the beach??? Bring your pipe, swaging tools, tube & family.. .

On the subject of brakes:

The 'upside' was that the master cylinder was in excellent shape, full of soft decomposed rubber which preserved the bore. A week of soaking in Methylated spirits (wood alcohol) and I managed to clean the goop out.

I used a piece of wooden dowel with a piece of Scotchbrite (scrubbie) to clean the bore to sparkling cast iron grey, and then lightly buffed it with 1200 grade wet & dry paper to remove any imperfections.... Anyone need the part number of the Ford Master Cylinder Overhaul kit in Oz???? See second picture.. one plastic bag says it all.

Keith would you be so kind as to add the Kit P/n to the spares list on MLU?

The bellcrank assembly was serviceable after I removed the dirt and cleaned the clevis pins.

More parts to be hung up & painted....

I take the easy route and give master cylinders to a brake reco place who rebore and sleeve in stainless and return complete with a kit ready to use so I'm sorry but I don't have a kit number.

Keith.......

I meant in the Excel spreadsheet in parts sources and prices. I have added to the thread. For all the Aussies it was $30.00 for the kit. Which is an IBS brand KX4 kit..

I cannot see why you cant overhaul a Chev Master Cylinder??? Aren't they the same diameter cylinder?

I am sunburnt today, spent an hour or more in the place where the engine once lay cleaning away the mud and grease... There is real green paint there...

Oh and we need some pictures of Chris's F15 in the making....

Jeez Howard, the least you can do is drop by b4 Corowa... how am I going to drive there with no brakes .

Seriously, I cant see me getting my truck done in time.. (sad but true) so I will have to bring the mighty Nissan & Caravan...

Ian - outsource and get a professional job. As an example I had the master and two wheel cylinders refurbished in December 2008.

Master - dismantle, clean, hone and polish bore and reassemble with new kit that included all rubbers and pistons. $104.30.

Wheel - same as above plus boring to accept stainless steel sleeve. Complete rebuild with insert, all rubbers and pistons - $119 each.

Back in January 2008 I had two brake lines made - $71.40.
