I thought you may be interested in some feedback on your options...
I had to do my discs and pads yesterday as they were literally shot! Faced with the cost of 4 x discs and pads @ £500 or more I thought I would look at other options as mentioned here.
First option was to buy a bunch of parts online and then get a local indie to fit them. This is the shopping list I worked up:
- Performance Friction 330mm Brake Pads £155
- Autolusso Braided 'Swivel End' Brake Line Kit £75
- Brembo 330mm Brake Pin Kit £34.32
- ALFA ROMEO 159 Saloon 2.4 JDTM 20V 4WD 2387cc Year: 07- Front Brake Discs £101.97
- ALFA ROMEO 159 Saloon 2.4 JDTM 20V 4WD 2387cc Year: 07- Rear Brake Discs £83.05
- MTEC Brakes Black Edition Brake Discs £25.00
- DP31425C (Red Stuff) Rear Ceramic Brake Pad Set £51.59
- Total £55.72
Brake Replacement (Parts inc shipping etc): £540.06
My local indie was talking the best part of £400 if "everything went smooth" so on-top of the parts cost I was looking at £900, or as I preferred to think... £400 more than the required OE replacement.
My second option was to phone Ned @ Autolusso and have a chat with an expert about options. He was pretty adamant that the best route was stock discs, as they are already vented, and the groves/dimples/holes "don't do anything to help you stop, they just look pretty", PF Pads, Braided Lines and Super Blue Racing Fluid. All in with Parts & Labour it was "around £700" so I decided on that approach and dropped it off with Ned yesterday.
His tech's managed to get it all done in about 5 hours, despite seized calliper bolts and some extra effort to get the old pads out, so the total was a little more than I was quoted, but still less than my DIY/Indie approach, so I was fairly happy from that perspective.
I was told that in order to bed the PF pads in and not glaze them, the process was the opposite of normal, so "drive it like you stole it" was the bedding in advice given and actioned
A day later, Its like night and day. What I find the hardest to believe is how I used to think I had good brakes, which, in hindsight, on a heavy 2.4 (or 3.2) the stock 330mm set-up is not. The combination of lines, fluid and pads is astonishing. The car feels lighter and more agile than it did before and speed just falls off at the slightest touch of the pedal.
The one thing I will say is that the PF pads are aggressive on the discs, so much so that when I am next due a set of pads, chances are it will also need a new set if front discs at the same time!
Hopefully, this will help with your thought process!
