M2 madness

[M3M3]

Started in on the hydraulics…Jim pulled the Volvo calipers

Pulled the tii master cyl. Gotta love ATE consistency. Decades of design later, the plunger, bolt spacing diameters are identical tii vs. 750.

750 installed on the booster. Still need to make up two short lines to connect existing line ends to master. Using stock bmw “T” fitting from the rear brake circuit to joint fronts together into single master outlet.

Struts and brakes bolted on

Finished removing rear brakes and set the caliper bracket in place. Caliper should be arriving tomorrow.

Accumulating a pile of brake parts to be sold…soon.

So, 750 master has single lines instead of tii which has dual lines?

[M3M3]

correct Al.

correct Al.

Sorry for the repeat question, just saw on the previous page that they were!

thx

Marshall;

Unrelated question: what is the black coating inside the wheel wells, I am about to start suspension rehab on the 73, might do that to clean up things a little and to prevent rust.

TIA

Does the spacer under the strut improve wheel to ball joint clearance?

3M rubberized undercoating.

what it looked like when i did it 3 years ago

makes wheel to ball joint clearance worse. bottom of strut stays in same place while spacer lowers ball joint by 26mm. probably could not use on <15in wheels.

it is a bump steer spacer..compensates for bad control arm angle due to lowering the car. it is also offset for more camber.

Wouldn't it push the wheel away from the ball joint (the one on the tie rod).

if you are referring to the main ball joint, the offset pushes the wheel away laterally, but the height of the spacer pushes the ball joint down, decreasing the clearance to the wheel.

if you are referring to the joint at the end of the tie rod, the yes, the offset pushes the wheel away from it. 16mm.

I see, that makes sense. Did Lee make these?

Sorry if I missed It marshall but who's rear disk bracket did you use? Thanks Dylan.

[M3M3]

Colin - yes, Lee made the spacers. he make three different sizes. the 26mm one i have is the only one with the 16mm offset for camber.

Dylan - IE made the bracket. a willwood caliper with 1.62in piston and parking brake will be attached.

we had some fun with...as andrew called it...the origami of brake lines at the MC tonight. made up two very short ones. used a male to male connector to extent the rear line in the car to the MC, then bent the in car lines to meet the "T" fitting and bent the other short line to join the "T" to the MC.

as soon as the new connector elbows arrive, the reservoir can be put back on and the front half of the brake system will be done.

another blunt box arrived today with various diff rebuild parts and two of these

new tii rear hubs. a bit thicker/stronger than 02 hubs. wonder how long they were sitting on a warehouse shelf in germany....

of course, i forgot to order studs for them...sigh.

Wow Marshall, you have completely confirmed my suspicion that the most expensive words in the English language are "You know, while we've got it apart..."

I am scheduled to drive the N2 home tomorrow, which leaves me with two questions:

1 - Do you know anyone who would want to buy your old malaga roundie shell with a tweaked, lo-mile M10, 4-speed, and lo-mile rear in it? I think I'm about to lose my free storage...

2 - Are you going to be around tomorrow morning-early afternoon? I would love to get an instructor's impression of how mine drives, especially given your experience in hotted-up 2002s...

Have a great evening,

Noah
