Brake Pipe Corrosion

Hi,

Couple of questions linked to the work I am doing on suspension and brakes at the moment: Is there anything you can put on brake lines to keep corrosion at bay? Also, does anyone know if the Gunson Eezibleed kit has a brake fluid reservoir cap that fits our cars?

I took the wheel arch liners off my car yesterday and at first sight I was a bit shocked at what i thought were lines about to burst all over the place. Actually, when I took the arch liners fully off and had a chance to touch the brake lines they're not too bad - all the brake lines and fuel pipes were replaced front to back in the last 6 years according to the service history in any case.

Nevertheless I had quite a lot of the 'white bloom' corrosion which brushed off really easy, and only a couple of spots where there was brown corrosion showing - again nothing more than skin deep i don't think, I had a pick at it with a needle file, but something I would like to keep at bay.

Should have taken a photo to put up here - maybe do that next weekend.

Cheers,

Eddy

PS: I will get a professional to take a look once I have the car running again and can get it into a garage

PPS: Got my castor mounts on (difficult to get enough torque when car isn't very high in the air) as well as replacing air filter, dizzy cap and rotor arm, oh and blown headlight bulb. Feels good to be putting new things on rather than scratching my head on how to get all the rusty bolts undone - last two weekends have been a mission involving nut splitters and eventually a hacksaw - I have a mechanic looking at drilling out the caliper mounting bolts, the heads of which were completely destroyed...I had to take the whole steering knuckle off in the end, and get brake pads out with a slide hammer.

PPPS: If you need new dizzy cap and rotor arm then Eurocarparts were very cheap for BERU branded parts, plus if you spend over £100 then you can get an extra 10% off with voucher code: CATOFFER10, or 5% off with CATOFFER5 if you only spend £50.
 
Yes mate the Gunson fits the brake and clutch master cylinders. I have one myself great bit of kit and cheap as chips. Just don't forget to check and adjust your tyre pressure afterwards [:D] As for the brake lines if I were doing them then I daresay I would use some paint or even some underseal. He sits and waits for someone to tell him why this is a bad idea [:)]
 
I thought pipes were generally replaced with copper (or is it copper nickle alloy?), so there shouldn't be any corrosion if they've been replaced? Thats what I did when I did my brakes last year - I snapped one of the rear pipes so had to replace it - was surprising easy. Funnily enough I had the splash gaurds out a couple of weeks ago as well, I just put some grease on the pipes with a brush. I did the same when I got the car 3 years ago and theres no corrosion so far!


I had trouble with torqueing the castor mounts too for exactly the same reason, I think I ended up using a jack on one as I wasn't happy with the amount the car was wobbling with me under it [:)]
 
Brake lines are indeed usually replaced with non-rusting ones, made of a material called Cunifer. It's softer, easier to bend and work and doesn't rust at all, so a much better bet. (Interestingly, the reason that steel lines are used on new cars is because it's a requirement to have steel brake lines on cars in the US, and most manufacturers therefore fit them to all cars. Volvo are the only manufacturer who fit different brake line material to different region cars.)

A smear of waxoyl on the brake lines is always a good idea. On the pipes themselves to deter rust and on the end fittings to stop them from seizing up.


Oli.
 
I liberally coat brake lines with waxoyl as it also has a built in rust killer BUT if subject to splashing and stones its no good as it will be blasted off.

If in doubt replace with Kunifer (copper/nickel) pipes.
 
I used waxoyl on my 24S, and will doing the same with the 44 once the other work is done,a sits been said use it on the connectors as well, makes life much easier if you ever need to replace
