E28 M535i Brake linkage part?

Recommended Posts

Hi all,

This is my first post.

 

Hoping someone might be able to help me with my missing part...

I've had my e28 up at my local garage to get the brakes properly tested. I'm not a mechanic so I wanted a professional to give them a once over as braking was very poor. 
After a quick check my mechanic told me there seems to be a part missing, its a bracket that stretches from the passenger side suspension strut to the pivoting part of the brake linkage arm which runs along the bulk head inside the engine bay. 

I've included a couple of pics to make life easier. 


Basically my questions are...

Does this part actually exist on this car? sounds like a dumb question but if someone els with an e28 m535i could confirm this it'd make a nice start. I know that the part exists in the e28 pictured but the m535i's braking system was different. 

Does anyone know where I could get it? 

I've tried Fritz Bits and Linwar. In fact the guy at Linwar told me to ask the forum so here I am...  

So thats my problem, i'd love the car on the road this summer and this is becoming quite the pain so any help on this would be greatly appreciated.

Thanks! 
Dan

What year is the car? Iirc there are two set ups one with the master cylinder on the drivers side and one with the cross linkage to a master cylinder on the passenger side.

Perhaps the mechanic is confused?

What's the brake symptoms you're trying to fix?

If you can identify the part then I'd try BMW themselves or try Tims on here.

Hi Duncan,

Thank you for getting back to me.

It’s a 1987,
It’s definitely the one with the linkage bar that runs to the master cylinder.

My mechanic could be getting confused as he’s not a bmw specialist.

Also I don’t ever remember seeing one on there.

The car had been standing for years and as a result the brakes had seized.

It needed a new master cylinder, new booster as the old one leaked terribly, new bomb and so on...

It now just about brakes but barely, my mechanic thinks that it’s to do with my floppy brake linkage, the thing that runs along the bulk head to the master cylinder, and with this support strut (that I’m not even sure was there in the first place) it’ll all be good again.

Hope this helps and thanks again for your response!

Have you put the chassis number into www.realoem.com to see if you can identify said part?

I've not had my m535i for 5 years now so don't recall exactly how it looked (mine had x link too)

You'd think though if it was bracket you see significant movement when pedal was pressed?

Brakes are ok as stock but not perfect.

If it's dead travel some of this can be adjusted out on the back off the brake booster (behind the bomb) from inside the car behind glove box.

Actually I’ve replaced the booster system with a normal brake servo from a 528e, I’ve heard it’s a pretty good way to do away with the leaky booster problem, I did try various boosters and also replaced the guts on a couple as well before doing this.

Also it’s worth mentioning I did replace the linkage arm assembly a few years ago but don’t remember ever taking off this bracket.

To be honest when I went up to the garage it was raining very heavily and so i only inspected it long enough to take some usable photos.

I think another visit to check just how wobbly it is wouldn’t go amiss.

But yes part 6 definitely looks like the thing I’m after, or at least pretty sure I’m after? .....

I cant thank you enough for your help and advice.

I can’t get it off of real oem so will have to continue hunting elsewhere, think it’s going to be a bit tricky.

I don’t suppose you know where I may be able to get one?

May have to go to BMW....

Thanks again
