Pulling off rotors

[86chevyk10]

Whats the best way to pull off the old rotors on a car that does not have the tapped holes for a bolt to push the rotor off the hub? Ive tried a mallot and penetrating lube around the mating surface and i cant get it to come off...any suggestions?

BFH . ( as in Big F'in Hammer)

if not saving or resufacing = BIG F...IN HAMMER thay will come off.

unless its a rare vehicle with rotors on the back side. then got to pull hub/rotor unit and remove from backside.

Knock the lug bolts out and the rotors will fall off.

not on all of them. some rust the inner hat section around tight on the outer dia of the wheel hub face.

style you are thinking of is for out axles.

he seems to be on a newer rig as he said no little hols to press off with bolts.

BFH most likely, what kind of car are we talking about here?

i always use an air hammer,with ear plugs. or a BFH!!! and they can get very hard to take off, especialy if you have lots of road salt. already had to cut one with a cutting disc, torch and cold water too.

You can also try and heat the rotor up with a torch (or those small yellow bottles of MAP gas, a blue bottle propane soldering torch won't get it hot enough). THen BFH it.

easiest, and best way,is to take a good sized hammer and smack the flat front and the outer edge of the hat. it will come loose.

Its actually on a 08 avalanche. It has the threaded holes but the PO stripped them out so I can use them. Ill try the BFH some more. I was also thinking maybe drive the truck and get the rotors heated up with some hard braking and bring it in immediately and take the rotors off since they should have expanded some. Thanks for the advice.

fyi when you get them off a bead of anti-seize around the center lip were the rotor sits and centers to help it float and keep from seizing up.

 

[86chevyk10]

good tip, i cant believe i havent thought of that before...thanks brother

 

[sweetk30]

thats a rust belt thing that helps but not a 100% fix/cure

and copper anti-seize hold up better than aluminum based silver anti-seize.

bfh will do it.make sure the backing plate,caliper mount, is off or it will not come off either.

did you take the screw that hold the caliper to the hub out. im not for sure if your application has it but i know alot of GM trucks do. just throwin that out there.
