Default 98 brake calipers--torx bits required?!?!

My calipers look to be secured by 4 torx bolts where I expected to instead find 14mm and 17mm hex bolts.

What the ____??

I thought VW = torx, not Lexus?!

Do I have some kind of weird aftermarket calipers or something from the previous owner?

Has anyone else found that doing brakes on a 98 ls400 requires torx bits?

I had to put my damn wheels back on after seeing the torx bits because I never owned a torx bit in my life; I only worked in Japanese cars.

The torx bolts hold the caliper pieces together, the caliper mounts to the carrier assembly using traditional hex bolts. As long as you aren't taking the calipers apart to rebuild them you have nothing to worry about.

So if I want to change my brake pads do I touch the torx bits?

I read the sticky just now and it seems that I just have to remove the Phillips screws to get to the brake pads?

There is no screw involved in removing the pads. Just remove the brake reservoir cap to relieve pressure and then remove the springs and sliding pins that hold the pads.

if you cannot follow the video above then I highly suggest you do NOT work on your brakes for your safety and the safety of others!

Pardon all the aloof responses you are getting. It is easy and common to not be able to see the two Hex bolts to remove the brake calipers. They are towrad the center from the back. Near where the struts attach to the knuckle. They can get really rusted and hard to remove. Don't strip the heads. Take it to a brake shop if they won't budge.

Thank you so much. Today was the first time I changed brake pads on a car. It went smoothly, and the process of breaking in the brakes revealed no issues! The car stops better now with a fresh pair of front brake pads. Now, I just need to do the rear pads. The car still doesn't quite stop on a dime. I drove a friend's old Hyundai elantra from 2003 and that piece of crap had brakes with BITE. Hopefully changing the rears will give my car a similar amount of bite!

I find my brakes pretty impressive for such a big car.

the elantra is a much lighter car!
though I never liked the braking feel of the LS, at least mine (probably needed a fluid change). it does stop but does not inspire confidence like other cars for sure.

ALS400 is heavy not going to stop like a compact car, but it will turn on a dime. Love how easy it is to get into a parking spot.
