Vintage Brake Caliper Rebuild: Rust Removal Impressive Results with WD40 Rust Remover
 

I am rebuilding a set of completely frozen and rusty Girling brake calipers (1972 vintage). The rear calipers have the pivoting mechanism on them for the e-brake, seen below with the twin metal ears that were also frozen causing the brake cables to snap.

I decided to try the WD40 Rust Remover after reading the positive reviews on Amazon and figured for $30 for the large container...let's give it a shot.

After 2 days of soaking it, I was VERY impressed, not only did it get rid of the rust but it freed up the e-brake mechanism whereby it pivots properly. I actually couldn't believe it. the stuff is also non-toxic and non-corrosive.

Highly recommended!

Here are some pictures.

Wonder how it compares to evaporust?

Not sure...but was wondering the same thing.

What would be the rinsing/cleaning next step process???

Let's say to just repaint the parts with rattle can ?

Not anodizing or chemical coating.

Interesting. I'm on several "old tool" groups (not like this group that's full of old tools, groups about old tools), and the subject of rust removal comes up often. Lots of suggestions of vinegar (frowned upon), evaporust (less frowned upon), and reverse electrolysis.

The vinegar or any other acid treatment is frowned upon because it also damages "good metal". Evaporust also has been reported to make changes to some metals. Some folks have cleaned items and then had the items break in an uncharacteristic way, the theory being that the break was due to a change in the metal caused by the evaporust.

I don't think I've ever heard any downsides to the reverse electrolysis. I'd like to try it, but haven't.

Probably the exact same stuff.

I used Evaporust on a pair of spring calipers. The spring broke. :(

Hydrogen embrittlement?

Gonna have to call you just slow soon.
