302mm Brake Upgrade Success

Is the 302mm upgrade worth it? It only cost me $78 extra as I needed to do the rest of that stuff anyway. There’s an improvement in the way the car stops and I think it’s worth it – especially when I factor in the savings I “earned” by doing it myself!

MVS Volvo Forums Contributor ojdorson breaks down the parts and process in upgrading to 302mm “big brakes” on his Volvo:

I just finished doing all the front brakes from the flex lines out.

Thoughts on the Brake Upgrade

  • The rotors look fantastic. They’re really clean and the black e-coating is smooth and seems durable. They ship in shrink wrap inside a box. In my first shipment, I got one that was NOT e-coated and looked to have been “handled.” Amazon’s service is tops and they rushed me out a new one and gave me a return label for the bad one.
  • The pads are nice with teflon backing and good tight springs on the inside pad.
  • The calipers were so cheap that I felt it made sense to replace them. The new calipers are beautiful and clean and well put together with new hardware (the wonky spring).
  • The stainless brake lines are fine – they do not have any rubber doughnut bumpers or anything so I ended up covering them with a piece of silicone hose I had leftover from my Stylin’ Motors kit.
  • The caliper brackets were perfect and are clear-coated.

  1. Anyone familiar with the ring thats bolted behind the left rear brake spindle? the hub that the lug bolts are pressed into. I found that ring cracked in 2 peaces. It’s held onto the hub with 2 10mm bolts from the front side of the hub.But seems you have to remove the hub assembly.
