Hi, Not a Lexus owner (long time Toyota owner!). I've been looking for some calipers to fit to a build I'm working on for a '90s Japanese domestic vehicle. I've been struggling to find something substantial that I can make an adapter for to mount to the stock hub/knuckle mounting ears. I came across the ISF Brembo calipers (front) and am very interested due to how the mounting lugs are staggered/offset and with a decent portion between them with space. They look like they are ideal candidates to try for my goals.

I've been watching and searching for a single front to come up at a reasonable price, alas nothing since I've been looking. Are there any technical drawings for these calipers? If not any details on some measurements: height, width, depth, spacing of the mounting ears/lugs, offset between the top and bottom mounting location.

Many thanks for any help, I'm trying to stop an old rotary barge with additional power.

Rgds, Ant

 

Something like this help? Brembo Racing Auto Catalog pdf has a bunch of drawings and tech specs.

?

 

Something like that would be perfect! If not available for the OEM Brembo I can model the approx dimensions and 3D print to test fit on my bench suspension/knuckle mock up. I'm specifically interested in the front OEM caliper as attached. I'm confident the matching rears will work - if the fronts work out I'd be ecstatic.

OEM Brembo (Front)

 

Disregard. I misunderstood

 

What's is the them that was made?

 

Disregard.

 

Thanks for the picture but I'm asking for measurements.

 

Well I've never seen the OEM Brembo spec data sheet for the Caliper...


But the OEM front rotor you'll need is here: (same for L&R)

 

I took some pictures for you. Apologies, I don't have any measuring calipers big enough so can't measure accurately so I just lined things up with a ruler to give you a rough idea. Not sure what specific measurements you need but let me know if you need anything in particular.




Also, I have a busted front right caliper from a failed caliper painting project (long story) that you might be interested in. I threaded the brake line fitting whilst reattaching it and then also managed to fubar the helicoil attempt. Ended up buying a new caliper. I suspect it could be repaired by filling the hole with weld or something and re-drilling the hole. Either way, gives you something that you could work with for your measurements. PM me if you want to make an offer--note that I am in Australia and you'll need to cover the shipping cost.

 

Many thanks. That will help if the calipers work for an idea of custom 2 piece rotors.

 

This is superb, I can't thank you enough as this goes a long way to demonstrating they may indeed work for my application. Would you mind taking a couple of other measurements please?
For the below:

1. Center between each mounting ear
2. Center of lower mounting ear to low point in the curve between mounting ears
3. Center of upper mounting ear to low point in the curve between mounting ears

For the below, how wide the mating surfaces are both mounting ears



I think every other measurement I can scale and work out from the original pictures you sent.

Thank you for the offer of the caliper, I'm in the US, shipping might be horrid :-( If you were gracious enough for the above requested new measurements I should be able to print a 3D mock up of the approx key dimensions to test mounting which would be a massive step forward for my application and enough to buy a complete set of front and rears to start real fabrication work. I cannot thank you enough, I'll PM you about funding a few beers/coffees.

Cheers, Ant
