rebuild front calipers?

Continuing my parade of "it's old enough to smoke and taking it on track broke it", I've found my piston dust boots are cracked on the front. Normally I'd just buy some reman Cardones, but I'd be sad (likely) losing the COBRA logo, already own sets of the seals/boots, and the job doesn't look that bad. Anyone here have experience on doing this job themselves vs. buying remans?

Wet the pistons and seals with a little brake fluid or some of the lube that some kits supply
You got this.

There really isn't much to it. Make sure everything is clean before putting the pistons back in.

Maybe get some replacement calipers for now and rebuild the cobra calipers at your leisure.

It may be your chance to upgrade...$$

Have them powder coated, get some steel braided lines, rebuild kits are cheap.....easy day.

Very easy (I think). Use an air blow gun, to drive the pistons out. Inspect everything carefully, use some scotch brite to freshen anywhere that needs it. as described above, lubricate the pistons before re installation. You probably will need a tool, to drive them back in. Re install on the car, and bleed.

Likely lots of videos "out there" that you can watch to make the final decision as to if you want to take on the project.

I would not give up the Cobra logo.

Easy pezzy. Just watch a couple of vids on YouTube, take your time, not a complicated job but it is important to do it right obviously. Make sure everything is as clean as possible.

Thanks all. So should I try putting (M10×1.0) nuts on the banjo bolts after I remove them from the caliper or just let all the fluid drain? I know I'll have to bleed either way, just not sure if it's better to try and keep most of it in there or let it out.

Getting air in the abs block can be a bitch so I’d try to avoid that, even if you need to put liquid line clamps on the hoses

Thanks, and good point on the ABS. SS hoses so no clamps. I'll see if I can find an appropriate nut, or maybe just try doing the trick where one has something hold the brake pedal down a bit to stop the flow from the reservoir

I use golf tees to plug brake lines, even steel ones. You may still get a little leakage but it won't drain the reservoir.

If you have FORScan you can put the ABS module into a bleed mode and it cycles through the valving.

I use a pressurized bleeder all the time now to bleed lines and change out brake fluid. These work great, especially if you work alone in your shop as I do.

And if you don’t have a pressure setup those one man bleeder bottles are a good compromise for the price

Ive used Speed Bleeder's for years on three different vehicles including the clutch slave cylinder on a Triumph Tr6 and Bmw with great results, for me they are easy one man operation and better than the vacuum pumps. Got them on my Mustang. here they are for the front here are the ones for the back

thanks. I actually bought a Motive a bit ago but this will be my first time using it, as I need to get fresh fluid in both the Cobra and M5 for track time.
