25 Year Old Brembo Brake Caliper Restoration / Rebuild

  / rrcrestoration  

Welcome to this weeks restoration project. This time i am tackling a pair of 25 year old Brembo brake calipers and hopefully restoring them back to their former glory!

First job as usual is a bit of theatrical unboxing and a good visual inspection to make sure that the calipers are suitable for restoration and dont have any cracks in the castings. Im pleased to say they checked out well and the only issue to be found is that one of the calipers had stuck pistons hence the reason the silver has started to turn gold with the amount of heat that had built up at some point.

So with inspection complete i started to tear the calipers apart, i was expecting to have a real fight on my hands but i was pleasantly surprised when there old Brembo's came apart surprisingly easy. The pistons were very nearly completely seized up it took 150psi of air pressure to budge them!

Once apart i could finally pull the pistons and seals out the cylinders are in good condition with no wear at all so thats nice. I then took the caliper halves to the parts washer to remove years of brake fluid, oil and road grime. Once dried off i masked off and plugged up all threaded and delicate areas and proceeded to blast them back to bare alloy in the media blaster.

Once back to bare metal i could mask them up properly and get them ready for primer and paint, All coatings used in this painting process are all perfectly cable of dealing with the temps and abuse associated with brake calipers so no need to flood the comment section with worries about this issue. The bare metal was prepped with an etch primer, then re-coated with a high build primer to smooth out the casting marks. while this was curing i took the old bolts and flung them into a rust eating solution to prep them for later plating.

When the primer was dry i proceeded to wet flat them back to remove all defects and leave a nice smooth surface so the final coat will be super smooth and shiny. I gave them 3 coats of colour matched red and while that was flashing off i made up the Brembo logo stencil and cut it out of vinyl on the plotter and applied it to the calipers with mm precision then it was coated with pure white base coat de-masked and clear coated.

While the paint was curing i moved onto the plating process and broke out the super sketchy bench grinder again :) the plating process will be explained in detail in an upcoming video so i wont go into detail here but you can see the bolts came out like new and i chose to go with silver passivate instead of the yellow as it would look weird against the red. I then polished the stainless steel parts with the buffing wheel on the pillar drill.

Then it was simply a case of re-assembly being careful the loctite, grease and torque up all specified parts as well as being super careful not to damage the awesome finish :)

So i hope you all enjoyed this Episode and i will be back with more content very soon.
