i had new rotors and pads installed and now yhey keep over heating.they are going to replace them again but the brake fluid has been over heated’ should the fluid be changed?

Yes–drained and bled with all new fluid now and every 30k miles.

No – brake fluid is not affected by brake overheating. It is not necessary to replace it for this reason.

Sounds Like The Brake Pads And/Or Pistons Are Hanging Up In The Brake Calipers. Are The Calipers Going To Be Replaced Or At Least Checked For Fully Releasing And Not Dragging ?

There’s a good chance that replacing just the pads and rotors will not remedy the problem you describe.

What symptoms caused you to replace the rotors and pads ? Were they worn out or was there another problem ?


Unfortunately, that statement is wrong.
The brake fluid definitely needs to be changed if your brakes have overheated–especially if the overheating has happened on more than one occasion.

brakes were pulsating no other problem truck has 64k on it

they were worn out and vibrated when applyed

As CSA Says Look at the Calipers. Improperly functioning calipers can cause rotor warpage, as can improperly tightened lug nuts.

thanks will do

You should consider replacing the brake hoses as well. There is probably a restriction in one or both of them, causing your rotor warpage and brake overheating problems. This is more common than caliper sticking issues, although both are possibilities.

thanks will follow up on both items

on second thought i would think it could only be in an area common to both sides like the brake line from the master cyl to the t going to both brakes. is this correct?

Time out!

If I correctly understand the post, you had the pads and rotors replaced and now the new rotors are pulsating. This by itself is not an indication of overheating or of stuck calipers due to collapsed hoses or any other reason.

The most likely possibilities here are that the new rotors were cheap rotors, which are more prone to warpage (we have an entire thread that discusses the technical reasons), the new rotors were not properly cleaned of their protective coatings when installed, or the wheels were overtorqued. I’ve never seen any actual data on this theory, but there are those here who apparently have. So I’ve included it.

It’s always prudent to check the calipers for sticking when new pads are installed, but I think everyone here is responding to the “overheating” comment and I don’t see any evidence in your post that your brake fluid was ovverheated.

replaced pads and rotors same problem

they are still over heating not pulsating
