Front Door Stop Buffer Question

7 posts / 1539 viewsLast Reply

Recommended Posts

A Stop Buffer is what BMW calls it. Part # 51216750058. It holds the pin in place that the door brake attaches to.

Question: What is the correct way they attach to the body of the vehicle?

My driver's side is held on with a nut and bolt, but the passenger side has no such nut and bolt and looks to be welded in place. I suspect welding would be the correct way, but I just want to make sure.

Thanks for any help.

especially on the driver's side they broke loose from the body. Since you can't get to the back side without cutting a hole in the inner cowl panel, all sorts of creative ways have been invented to reattach: pop rivets, sheet metal screws etc.

The only really effecctive way is to have it welded back on by a welder who knows what he's doing so that there's minimal paint damage (and no fire!).

PS--the new style door check straps aren't nearly as hard on that bracket as the original BMW design...

No, I don't think so. #9 is a rubber part that goes on around the bracket to which the pin attached. The bracket is welded to the body of the car.

Slip the rubber over the door brake tongue, then insert the tongue into bracket and insert pin. Push the rubber buffer over the bracket.

Mike, I currently have the fender off and I am replacing the "A" column metal that covers the stop buffer so access is good right now.

Other than a hole in it for the bolt, the buffer looks to be in good shape.

Can I simply weld the existing piece back on or is it better to just replace?

BTW, what do the new style door check straps look like?

Thanks again,

Bart

Hi Bart, The pillar mount is the the part that is spot welded from the inside of the A pillar, the door brake arm fits into it and is held with a factory pin, I think the buffer was a square rubber seal that was glued to the door around the hole that the door brake arm passes through, I have never seen one in a 2002 , only illustrated. The original door brakes were weak and failed often and are NLA, BMW offers a replacement which is a modified part from a later model , they are too stiff for the weak pillar mounts in our 2002's, I have seen them installed and the a pillar flexes around the mount when the door is opened or closed. Below are links to post on 2002 faq with the best replacement parts to use.

Thanks everyone for all of your help. I believe I have remedied the situation. I took the nut and bolt out, filled in the hole and welded the bracket back on in the proper fashion.

Harry, I am definitely going to buy a set of your brakes in time. I am restoring my car now and the parts list is long!! Thanks for your help.
