I have a 1970 Beetle. I have read about swing-arm
suspension and IRS suspension at the back of the bug, what is the difference between them and how can I tell which type I have on my car?

My second question is that that I have taken off the brakes already, like the the springs and levers and backplates etc. They are quite rusty and I want to clean them up, is there any good solvent or such like I can use to clean all the rust off? Will it be a a good idea to paint them to stop them from rusting again?

The IRS rear suspension first appeared in 1968 in the semi-auto Beetle. In 1969 the rest of the US Beetles got the IRS; and in most other countries, IRS became standard in 1971, although the base model 1200cc which was sold mostly in Eastern Europe remained swing axle.
The IRS suspension consists of a stub axle to which the brake drums attaches, and a drive shaft with a constant velocity joint at each end which connects between the stub axle and the gearbox. This enables the wheels to move vertically up and down instead of swinging in an arc as per the original VW design.

For freeing rusted VW Beetle brake adjusters I'd use PB Blaster.It's great stuff! Like WD-40 on steriods.The brake hardware(springs,hold down pins,etc.)should be replaced if possible. Painting the backing plate while your in there won't hurt anything but try to remove as much rust as possible first. Also, I would use a hi-temp paint so the heat doesn't cook it off.
