I went to the dealer, and they said my calipers were seizing up. They want 1500 to replace them and the Brake hoses.
I want to do it myself. Is there anything special I have to do for the antilock breaks, or can I just clam the hose and bleed the air out after they are on? Is it possible to just clean them instead of buying new ones? Is it also possible its just the caliper pins are dirty?
Any other tips on replacing or cleaning the calipers would be appreciated
Thanks

What problems are you experiencing ?
Mine's a 91 too , and all of the sudden , they
feel kinda of Mushy , see my posting.

IT's not that bad and I haven't taken it apart yet.
But I suspect mine is the Master Cylinder and or
a hose starting to go bad? Many have said
check and bleed the brakes , which I will
do first, and probably replace with SS brake
lines, about $125 for the 2 front ones.
Kinda expensive I think, supposed to be much
better than the plain rubber.

I think the same is happening to mine. They stick very slightly *I think*.

The advice given to me was to buy rebuilt ones for about $50-100 each caliper. Mine still work OK so I don't plan on dropping the cash.

SS brake lines supposedly help the pedal feel more stiff and responsive. Brake lines are supposed to last at least to the life of the car. How long this is, I don't know. It woudn't be a bad idea to replace them with something better though. Also from what I've read here on CL is that brake fluid is a VERY important part of the brake system. If the fluid is dark colored it needs replced. Air and other contaminents in the fluid and lines will make the brakes unreliable.

I do know that the first gen LS brakes went thorugh 3 revisions. The rotor sizes were increased and dual piston calipers were added in 1992 or 1993.

I have bled my brakes before on my 90 LS and everything was pretty simple. I think you should do the same and if the problem persists, then it might have something to do w/your master cylinder.

Thanks for the replies, I took off the caliper and took it apart (one of the cylinders was soo tight that it took me about 3 hours to work out.) . The seals had holes in them and it had rusted pretty badly. After I cleaned it, I put it back together, but the rubber boots were too bad to put on. I needed it to drive home so I put it on the car without the rubber boots, bled it and drove home. The next day I called around and finally (you all know how hard it is to get parts for the Lexus) found some rebuilt ones for 53.39+core a piece new break pads included (was actually more without them).

Once I got them home. About an hour to finish. Breaks work great. If anyone else wants to check if theirs are sticking, the easiest way is to jack up the car and see how hard the wheels are to turn.

Now all I have to do is replace the TPS sensor, replace the battery, replace the heater control valvec, replace the hood struts, and Clean the throttle body
Ill probably be asking questions about one or more above HA
