FS: 334mm Brembo brake upgrade for W124, W201, R129
What's included:
Used front Brembo calipers, rotors, and brake pads, size 334x32mm. Total weight of this setup is approximately equal to the iron 320x30 setup used on late 1994 E500 models in USA. The front rotors are 50% worn - they measure 31mm, min spec is 30mm. I do not know if they are straight or not. I intended to use them temporarily, and eventually get new drilled rotors. I have part numbers for OE rotors, either stock or cross-drilled, available at any MB dealer. These front brakes require 17" wheels.
What cars they fit:
These brakes will fit all 400E, E420, 500E, E500 models (W124 only - not W210) as well as M104-powered W124s from 1990-up. They can be made to fit other W124's and W201's with additional modifications (will require lower control arm OR spindle swapping.) They also are a direct fit for all R129's through 1998.
What else is out there:
Bekkers sells the identical front brake setup with new calipers, rotors, and pads for $1989 - click here for details. The StopTech 355mm setup is fabulous but requires 18" wheels, and costs about $2500. AFAIK, these are the only two commonly available "off the shelf" big-brake options for the 500E. The recently-discussed C32 upgrade requires significant modifications, and you end up with "upside down" calipers with the leading/trailing pistons reversed - not my cup of tea, but others are happy with it.
FAQ's:
There have been a lot of questions about the master cylinder and brake booster compatibility. This will NOT be an issue for V8 model W124's or any R129. If you have a 6-cyl 124 or a 201, you may want to upgrade to the V8 M/C and booster, but it's just a personal preference for the pedal feel. Porterfield R4-S pads are available for this application as well as Genuine Mercedes pads. The front brakes should be a complete bolt-on for V8 models, other than removing the extra locating pin on the front hub as the 334 rotors have one hole, not two. For non-M119/M104 W124's and most 201's, you'll need R129 knuckles+hubs for clearance between the rotor and ball joint (or late 124 control arms with welded ball joints, which are far more expensive.) I don't have the matching rear calipers (300x22mm) but those are commonly availble for ~$150 plus rotors. I know of some rears available and can give you contact info to buy the rea calipers, and the part numbers to buy new rear rotors.
Pricing:
$550 for the front calipers, pads, and used rotors. Rotors are optional, if you'd prefer to buy new cross-drilled rotors, that's fine... they're available at any dealership, and I can provide the part numbers (or I can supply new drilled rotors, your choice - add $200 for new rotors.) The R129 knuckles+hubs are available separately for $125.
