I thought it's going to be an easy life this week since I won't be working on another NSX until next week.
Then, something came to my mind and suddenly I found myself placing the order for the front brake disc/pad and started disassembling the calipers....
My boss was not impressed at all as it's her birthday very soon and we were supposed to be doing some shopping.....


Moving on.....


Ideally, I wanted to send the caliper and bracket to Bigg Red to have them polymer coated but time is something I don't have at the moment so will need to do quick touch up by myself.




The Front pad.
I have been using Type-R GP pad for many years but it's so harsh on the standard disc that I had to regularly replace the disc even before the pad got worn.
This time, I decided to go bit gentle and selected EBC Redstuff and EBC plain disc as I'm already using them at the rear side.

Thanks to EBC Brake Shop, the disc and pad arrived the following day.





I had to exchange several email regarding the wear indicator on the new pad because it was only attached to one side.
When I received my rear set a while ago, it was attached to both sides (as in the above photo).

According to EBC, it is fairly common for them to send out the pad with just one wear indicator attached. Really???
Not a problem for me as I regularly check my pad and disc any way but if there was a problem on the caliper, it could be a problem for other owners.





The new front disc.
I ordered parts #D7352 but it came in the box with UPR7352 label.
I think UPR series is for the US market but the same product as D series in Europe so just a label difference.

Again, last time when I ordered the Rear disc, it came with D series number so another inconsistency by EBC. Won't affect the brake performance but just gives some question marks to the customer like me.




Based on what I saw on my rear disc, decided to do quick painting at the disc hat and edge though I didn't have suitable width brush so couldn't paint the air vent section.
In fact, I didn't have time stripping off the Zinc plate or applying primer so probably let them rust a little and paint again.





Once again, it proved that the special treatment that I use during the caliper OH protects the pistons, caliper internal wall, boot recess, etc against the rust/corrosion.
Same pistons used for years and still like new, very shiny finish.

If overhauled properly and regularly, it will save your time and money.

OEM piston is very expensive and quite often, out of stock. The aftermarket ones are either out of stock or no longer available these days.




Bit of wear on the slider pins but nothing unusual so just going to re-use them.




Testing the overhauled front caliper with the same treatment as before.
I want to paint the caliper and bracket...... But not enough time......




Front installed.




Rear installed and due to lack of time and brush, had to use my finger to touch up the paint on the disc....


Hope I can quickly touch up the caliper with black paint later.


Needs to push as another NSX will be here very soon and I need to free up the lift....


Joy of working on my NSX in such limited time.

    Hi Kaz, how do you like ebc redstuff pads?

    Hi, Solidol.
    So far, with the Redstuff, I have covered about 7,000miles on the rear set and 2,000miles on the front one and happy with them for my priority and purpose.

    I don't need to use my NSX for track day so only street driving condition but fairly hard on the brake as I use ABS on purposely from time to time.
    I have later spec larger brake caliper/disc setup with upgraded one body ABS so I can use ABS unlike the classic ones.

    With my amateur level driving skill, the OEM normal pad tends to fade just after 1 timed lap on twisty circuit design but the OEM Type-R GP pad was fine under the same condition.
    Hence, I kept using GP pad for ages. In Japan, I never used EBC Redstuff so can't do direct comparison but with my every day usage, happy with the pedal feeling, the initial bite and how it behaves under progressive brake pressure.

    Very low dust when driven normally and with EBC Plain Disc (no need for slotted/drilled ones for my purpose, in fact, even when tested on track, I couldn't feel the difference with my low driving skill) that is one of the highest priority for me.
    When you prepare your disc and pad occasionally for spirited driving, you will get fair amount of dust during the process. You will be surprised by the huge difference in the amount of dust between normal driving against repeated hard braking while transferring the pad material to the disc.

    By the way, I was fortunate enough to try the Yellowstuff on the exactly the same day, same driving conditions on another NSX back to back with my NSX using Redstuff.
    I washed the NSX with Yellowstuff before start driving and because it was not my NSX, I didn't push at all.
    The bite feeling was good even at cold weather like now here in UK and similar to Redstuff although I would say not easy to spot any differences under these low speed conditions.

    However, I was quite surprised with the amount of brake dust. As mentioned, I washed the car before start driving and even just after short test driving session, I saw enough brake dust on the wheel.

    If you are doing many track days, probably Yellowstuff is a good choice but for me, I'll stay with the Redstuff simply because I place high importance on the low level brake dust.
    I drive almost everyday and I don't want to keep cleaning the wheels at the end of each day.....
