My MG lives outside and doesn't get much winter use. It's not scorned. Rhe discs suffer from lomg periods of inactivity, getting rust and I had a caliber stick.

Clearly use is the key to keeping them OK.

Bearing in mind it is a light oil which evaporates quickly, would a regular squirt of WD40 help or would that be a massively dangerous thing do do?

It would be wiped off after an application of the brakes. Unlikely to cause too much of an issue.

WD40 is a lubricant, so applying it to the brakes will prevent them working.

No, the brakes will be applied and your vehicle will go sailing on into the nearest solid object. After that, they will probably work fine.

WD40 may be absorbed into the braking material. Bad idea!

Rust on discs is purely cosmetic. Ignore it. It's FAR less harmful than applying oil to friction surfaces...

Bad idea as per above posts, it is also pretty flammable to probably would absorb in to the pad and could be a fire risk

Bad idea. The rust itself will quickly rub off after a few applications and it'll be fine. 59million-odd other cars in the uk have the same non-problem afterall!

I've found WD40 crap as a lubricant, it just dries up and disappears, ideal for cleaning stuff (wiping down alloy engine parts etc) that's about it.

GT85 is far better as a lubricant spray.

Having said that i would'nt spray WD40 onto brake disks, as mentioned it will contaminate the brake linings.

The key is in the name - it's a water displacement product, not a lubricant.

WD40 will be absorbed into brake pads and they'll be mullered. As previously mentioned, WD40 is not a lubricant but a water displacement fluid...in fact the 40th iteration, hence, WD40.

OP, with the car living outside, do you have the room to put the car into a winter tent? I found myself short of garage space some years back and bought one of these http://www.ebay.co.uk/itm/Portable-Garage-Carport-...

They work brilliantly and kept 99% of the winter weather off the car, no rust on brake discs and because they enable good airflow the car was superbly dry.

I have thought f something like that. I live in a big house with zero space for a garage. Designed before cars were common in 1901, Victorian/Edwardian corner tettace house on a wedge shaped plot. The front f the house is at the thick end triple fronted sort of with off street parking for 2-3 cars. I don't think a tent would really go down with my wife or neighbours. I have heard car covers can do more harm than good. I've a soft top cover, the car is cleaned lubricated and serviced properly.

The answer is to use it more. A tough one when most of my work is from home and my wife works just over a mioe away..

I've a trickle charger and a solar conditioner. The attemp is quite new and I can start it and leave it running quite securely which I do once a week or so just to get it warm.

Itj just that I have had several cars like this and come MIT time it's aoways the brakes that come up as an advisory. The AST MOT just after I got it had zero advisories, not bad for an old MGF.

I've seen new cars in stockyards with plastic wrapped round the wheels. Is that to protect the brakes?

No, it's to stop the alloys getting marked when the cars are strapped to the transporter/ship/train.

This thread is just retarded! Simply remove the discs and keep somewhere dry and warm for the winter instead.
