Removing rear brembo's

[andy_mac]

Not sure if i'm just being a simpleton or not but how do you remove a rear brembo when a legacy/brembo backing plate is used. The whole setup including rear trailing arm/hub came put together. Can't get that top caliper bolt undone as nothing i have or can think of will fit in there the way it currently is. Would need something with a thin surround to get in there but only sticks out 5-10mm past the top of the bolt head, the hole near it does not line up at all with this bolt.

Only way i can think of is to undo the one bolt and hope the caliper will move enough, not hopeful on this, to get the rotor out past the caliper with the pads removed, then i can undo the backing plate bolts behind it. Then get the caliper off the backing plate, surely there is a more straightforward method.

I`m sure I just used ring spanners

Tried with mine but it catches on the backing plate. Maybe i just need some with a straight offset rather than a progresive one.

I had this exact problem today, but it was worse because we couldn't get the driveshafts off because we didn't have a 30mm socket. Will get onto it tomorrow.

Yea thats why i thought there must be another way. Its one thing doing it on the ground but attached to the car that's be a real dog of a job.
Gonna get a differently shaped 17mm ring spanner today and see if that does the trick.

I did mine a couple of weeks ago. It was no biggy just the right spanners. The fronts were harder as you have to remove a strut bolt to get one of the calliper bolts out.

[andy_mac]

Managed to get it done with my orig ring spanners. Just ended up gouging a bit of the backing plate along with it. Definately wouldn't do it that way when on a car so still need to find a better solution for when i chuck them on properly.

I did this a few days ago. Modified a 17mm ring spanner to clear the backing plate.

I'll post a pic tomorrow.

You didn't post a pic, so I'll post one showing my problem, which wasn't to do so much with not being able to get the spanner onto it as it was to get the torque onto the spanner.


One head came off, the other one I managed to get the bolt out after 100 or excruciating quarter turns with the ring spanner and a pipe. God knows how the hell you would do this if it was actually on the car.

Off topic a little:
Iirc you'll need a 32mm socket for the axle nuts, and a big ass copper drift is handy for tapping the stub from the hub
If no air wrench, tap out the crimp in the nut and have access to a long breaker bar.
One side of my car was ok with a 2'...
The other side needed like a 4'

If your wheel cap allows access, drive to a local garage, rattle the axle nuts loose, do up easy tight, replace cap and drive home to complete the task.

Did you rip the head off trying to tighten or loosen the bolt?

Would a flexible ratchet extention help get the job done? Or are they too weak?

That reminds me, I need to grab a new ratchet after 2 shattered trying to undo a lower strut bolt

[andy_mac]

If you mean a flexible piece with a socket set then na. Even my 3/8 set with really short socket pieces are still to long to fit between the backing plate and the trailing arm. Thats not even with the rachet attached, the gap really is stupidly tight.
Been trying to find something like this, needs a completely vertical offset to fit past the lip on the backing plate



You shattered the socket piece or the actual rachet? Should use a breaker bar instead of a rachet if thats what you're doing.

loosen - whoever changed the pads on these tightened them up WAYYYYYYYYY too tight. You don't need a torque wrench not to be a dickhead and do stuff up that tight.


also what about - http://www.ebay.com.au/itm/Bahco-14-Pie ... 43ba64a934

Yep, forgot to post pics....

Here they are of the modded 17mm Sidchrome ring spanner. Worked a treat.

Also, that bolt was seized in that rear caliper Matt. Even with the right tool's it would of snapped. I sorted it though.
