Don't do that, time for a Bosch Motorsport ABS package.

Seems to be semi affordable these days.

Are you kidding? Pulling any fuse will brick the entire car, from the sunroof to the tyre pressure sensors.

I don't have enough soul left to sell. :(

by the time everything is done a M3/M4 is cheaper and faster lol

Yeah, this old girl is complete now from a performance POV (how often have you heard that?). I'll just maintain and enjoy for a few years and consider getting an M-something (probs M2) in the future.

See, I find that hilarious, as I've seen them do so much stupid things (BMW and Merc) with electric faults. Yet the C63 race car has half the modules pulled out, a bunch of fuses and wiring cut, and, it just runs happily! We can even pull the ABS module or fuse, and it's totally happy!

Have you done a paternity DNA test?

Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.

This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it.

So I guess I'm doing a bearing again. 

 

Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

I did that today. I couldn't get the scope in there but I could get a good look with a torch. There was heaps of shit on the walls of the sensor hole that I cleaned as best I could but I couldn't see any damage or anything untoward. 😞

I might buy a new scope actually in the morning, mine has gone a bit cloudy so was kinda useless especially as I couldn't get it in there. Might be a good first step actually.

Bosch Motorsport ABS time 

I will reiterate... Pull the ABS fuse...

At a minimum, good test to see if it's actually being caused by the ABS system...

At the other end of the scale, if the vibration is from ABS turning on, last thing you want is when you're trying to brake, having ABS kick in when it shouldn't and now you can't actually stop at all... At least with ABS unplugged the worst issue is you need to be aware you're the one that needs to modulate pressure in an emergency.

Uses the factory sensors? Which are currently the problem?

Replacing the entire system with a Bosch Motorsports ABS system fixes the issue @PranKhas 

Probably not the cheapest nor cost effective way to fix his ABS problem 😂

Hey keep the ideas coming, I'm always keen on projects!

But, problem fixed! 

I got a cheapie ozito scope from Bunnings and had a good look in and around the bearing and sensor hole. I couldn't see a smoking gun but the bearing looked a bit strange, especially when comparing with a new one. I thought the cover had come off the bearing magnets. 

Sorry for pics of a screen, I didn't have an SD card.

Good thing I had the old one to inspect.

So, given I'm like a pit crew with wheel bearings and luckily I had a spare bearing because I f**ked up my parts order, I decided to just smash it out.

Got the old one out in about an hour. So much easier when the parts haven't had a chance to rust together yet. 😂

And, well, found the problem.

In the second pic at about the 8 o'clock position, you'll see what I think is the tip of the old sensor. 

The new sensor has definitely been rubbing but it's all intact, just a little shiny so I'm hoping it's fine. 

The car brakes perfectly now and no errors. 

I think the job took about 2.5h in the end. 👍🏻

I really appreciate the help in here as usual. Thanks guys.

Johnny is sad now... Because you didn't get Bosch Motorsport ABS.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
