A buddy has a strange problem with his 89s V8. I'd like to give you a brief description of the problem. I'm very suspicious of the front saddles.
As soon as the brake gets warm, the front brake calipers block, but both. The car doesn't crawl there any more when you put in the D. On the stage we found that the pistons don't go back at all. After some time already, when the brake cools down.
I would like to mention that about 2 years ago outdated brake calipers (probably no original) were installed.
Now the almost new UFOs are done and have a hit. Now the front brake has to be completely revised again.

We removed both pistons and you can see traces, a ridge. Before we buy new saddles, slices and coverings for a lot of money from tradition, I thought I'd get an opinion from you.
I say it's the saddles. Still, I'd be very interested in your opinion.
By the way: The pressure storage was also defective, it is already an outdated built-in by Tim and everything is good again.

Best regards
Daniel
