Lexus LS400 Brake caliper upgrade

[AndyJax]

Just nipped down to my local breakers hoping to source some LS400 front4 pot brake calipers to replace my NA two pot jobbies.He did n't have any in stock ,then queried why did I want some for a brake upgrade for the Supra when they seem to be prone to seizing and hes had quite a lot of returns.

 

Has anybody who's done this conversion had issues with the caliper pistons seizing more often than usual or is it just a case of brake calipers tending to seize up more in a breakers yard because they re not working and exposed to the elements perhaps ?

 

Any thoughts and advice is greatly appreciated

I dont see why they would seize any more or any less than any other brake setup (assuming they has the dust covers put back on the pistons). My old jspec setup was bloody horrible for seizing, and they were used everyday.

I did this upgrade probably 3-4 years ago with no issues so far.

 

I did replace all the seals and cleaned out all the hydraulic oilways to almost lab standards but used original pistons. I also change my brake fluid every 24 months.
