Hi there. This morning went to the store and back and noticed my '98 blazer, 4.3 LS was kinda like when going slow felt like there was something wrong with a tire ( like it was oblong high and low spot, hard to explain) so i checked the tires and my driverrs side burnt my finger touching the rim. Checked the temperature of the rim and it registered 191 degrees, checked the brake fluid which was good and it had a temperature of 151 degrees. Any ideas why this is so hot. Thanks

 

My first thought would be you have a sticky brake caliper. I suppose a bad wheel bearing could also be the source.

No matter what, the wheel needs to be jacked up and checked for free-play and ease of rotation as part of diagnosing the possible cause.

 

hey how you been. that was my thought about the brake, dont hear no noise though. Waitin for it to cool down before i check it. Having to clean up first (limbs, shingles. etc.) after that hurricane

 

I'm doing ok. Thanks for asking.

I'm sure we'll all be interested to learn what you find.

It also occurred to me that a pinched brake line could cause these symptoms.

 

I had the same thing happen a few year back. It was the rubber brake line that had collapsed. It would let the fluid in but not back out. I couldn't tell the line had collapsed by looking or feeling it. Ended up replacing the rotor, line, and hub as the bearing overheated and to out the ABS sensor. I didn't notice until it was to late.

 

well i replaced the brake pads, (one was down to the metal) caliber looks okay (had one piston come out when i was backing them off to get over the brake shoes wasnt scored or rusty) but i still got that pulsating motion when moving. even rotated the tires. could it be the rotor got warped

 

If you had a brake sticking that wore out the pad on one side, then there's a good chance the rotor is also bad. Too much heat will warp them and give you that pulsing feeling.

 

hey there, thats my thinking too just waiting to get a new rotor and caliper. Thanks for the reply

 

never thought about the brake line, guess i'll replace that too....thanks

 

Quick thought: Was the difference in pad wear very large? If so the caliper might not have been stuck to the guide pins.
