My Son and I are attempting to remove the rear drivers rotor on his E36 to diagnose a scraping noise at the rear drivers wheel. I like when my Son works on his car. Something we can do together. He took the rear wheel brakes apart earlier in the day, but couldn't get the rotor off. I thought it would be an easy removal, scoot over, let Dad get in there. Thinking there may be a rock stuck in between the rotor and the rock shield. When we spin the other tire, there are metal powder like particles falling in one spot, so either something is in there grinding the rotor or the hub is going bad. There is a little play in the hub. So, logically, my Son and I am trying to remove the rotor to inspect underneath. After removing the caliper and carrier, it appears the rotor has bonded with the hub. He removed the retaining allen bolt on the rotor. He did retract the emergency brake adjusting bar to retract the brake shoes. Not budging. We turned the adjuster in both directions in case we had it wrong. Not budging. Then we called James for left/right orientation on the adjusting bar just to cross check. Nada. We used a dead blow hammer to no avail. We used PB blaster, heated the hub part of the rotor with a MAPP torch (Lightly), froze the hub, cussed a lot and prayed to the brake gods and still not budging. Scribed the area where it is supposed to free up. Heated it up hotter, then used a 4 lb hammer, Now it's a matter of DIY pride... No joy... Opened the Bentley manual... No new wisdom. Searched here, BFC and Fest. No insight. Apparently in the six years we have owned this car, we swapped the motor, tranny, suspension, cooling system, trunk, hood, interior bits, headlights, brake pads, but we have never had to take off the rear rotors... I then looked up the number for a shop I use when I can't figure something out or need advanced electronic stuff. Unless I figure it out before then, it's going in on Monday... I hate sending cars in... Stupid rotors... I'm ranting a little. I'll welcome any rear rotor removal advice here. I hate removing rear brake rotors... __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

You don't want to hit the braking part of the rotor unless your going to replace it because hitting it may warp the rotor. | | | 03-21-2015, 05:32 PM | #3 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Yeah, tried that when I heated it up. While we retracted the adjustment shaft. I think the shoes are also caught on the ridge created on the brake drum over time on top of the rotor being siezed. I know I've not removed these rotors previously as there is no trace of anti seize on the hub. Standard practice for me from past battles on rear brakes. I hate old rear brakes... 👹 __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

You can hit the hot of the rotor, as said. I also hit the braking part of the rotor, rotate it, and hit again, and repeat. Good thing I live in rust-free New Jersey where I don't have to deal with this ever. __________________ 2000 M5 -> 1996 318ti -> 1997 328i Instagram: ndrewchow YouTube: MINIzguy | | | 03-21-2015, 07:35 PM | #5 | Senior Member Join Date: Feb 2012 Location: Sacramento, CA Posts: 2,451 | Quote: Originally Posted by wolferj Good news!

I have spare rotors in the parts locker if we get brutal. I recall having similar issues when I did E30 rear brakes. O, I also broke a puller yesterday when I wasn't concerned about warping the freaking rotor... My Son is getting the car apart now to whack the rotor again. Good character building for him. The thing that sucks is we're working in the driveway and the pollen count is very high and totally screwing with my breathing. Allergies. It's gotta be bad if I don't want to work on the cars... Thanks guys, I'll let you know how it turns out. I hate freaking old rusted rear brakes... __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

Up on stands and off stands, start to finish 22 minutes. A few squirts of PB blaster while he was taking it apart and five whacks with the 4 pounder on the sides of the hat and it was off. I suspect the PB blaster from yesterday had time to work in and made today's removal much easier. The rear shoes are at rivets and need to be replaced. The hub is a little loose, but not wobbly. We'll replace the shoes to see if that was the source of the dragging, If not, we'll replace the hub. Lesson learned here (again) is spray the hub the day before you are taking it apart if the hub rust is holding the #$(%&$ rotor in place. And never be without a good 4lb sledge. Thanks everyone! __________________ 1998 318ti Sport - "Cali" Schwartz II/Schwartz sport interior, Cali top 1998 318ti Sport - "Max" Schwartz II/Schwartz sport interior, S52 1997 318ti Sport - "Tiny" Schwartz II/Schwartz sport interior 1995 318ti Active - "Blanca" Alpineweib III/Schwartz leather interior Other Current Bimmers: 2006 530i / 2000 2.3L Z3 / 1997 1.9L Z3 / 1999 540it 1997 318ti Sport - "Huera" - RIP 1995 318ti Active - RIP 1995 318ti Sport - "Tiny" Sold 1994 325i Sedan - "Jade" - Sold 1991 318ic - "Bert" - Sold 1985 635csi sold 1984 533i "Max" Sold 1984 318i sold BMWCCA #160411 SUPPORT 318ti.org!

Be well Bro... | I was swamped with work from November thru February. It has slowed some the past few weeks. Perfect timing tho...Snook Season opened on March 1st. I've been putting on a clinic lately. People just can't seem to hook into these fish like us locals can. Also, I'm currently sunburned from offshore fishing yesterday. We smashed the Red Grouper! Currently working out a minor cooling issue with Zippy. I think I have it hashed out after adding a new water pump and radiator. Finally, the s52 build is almost completed. I have a few more parts to purchase tho. It should be ready to drop into the Cali-Top come May or June. That's it my man...work, fishing & cars. __________________ Sean 1995 Active | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
