I have a S1 Stagea RS4 auto with the under dash hand brake + release handle, I've just had the rear brake pads replaced and last night I noticed the (!) symbol flickering on & off whilst driving.

Is there a sensor for this light? Or do I just need to find the hand brake cable and apply some grease?

Any thoughts?

actually, it is more likely to be low brake fluid - the handbrake light is also used for that.

Have a look at the fluid level in the large resoviour in the engine bay near the driver's a pillar. If it is low you either have a fluid leak (bad) or your pads and discs are low and ready for replacement

Aren't there two resivours and if so where are they, i know the one near the break booster but someone was talking about one below there or something. I think i have this same problem or at least i hope it's this simple!!!???

sorry I wasn't very clear - the warning light is either handbrake on or low brake fluid, and low brake fluid only happens from a leak or sometimes pads worn.

If you have plenty of fluid in the master cylinder, it must be the handbrake switch not releasing properly.

Thanks Duncan, I'll have a look to see what I can do!?

Has anybody located the switch I'm referring too?

The switch should be on the rearward side of the foot brake you use for parking. Its a peg type that extends out ward to form the earth for the circuit when you depress this lever.

Having rear pads replaced wont help your park brake position as the park brake is the internal hub type (Pretty sure). If you have noticed an improvement in your park brake its possible there has been an adjustment made to your cable under the dash rather than at the rear wheels.

Could be the switch has been knocked loose?

Try releasing the park brake then get your toe under the pedal and pull it back a bit.....

I still have the same problem. At first I had to put my foot under the pedal to make it release, then it stuck altogether.

I fixed it by disconnecting it. Maybe one day I will try again and also make the ABS light go OFF.

Which cable seizes? Is it the one from the dash to the splitter, or one of the wheel cables?

Generally, the inner sheath rusts and damages the plastic coating on the cable, which makes it jam. No amount of lube down the sheath will free them up.

I know it's pretty obvious, but if you can work out which cable it is; there are companies that can manufacture factory style, plastic coated inner wire replacement cables.

I'm sure Nissan replacement cables will be fairly pricey.

The rusty cable may be the answer I am looking for. The 25G came from a salty road area in Japan. While repairing the smash damage we found several patches of quite serious rust and had it all cut out and repaired. Soon as it is driveable this week will put it on the hoist and check it out.

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
