Brake Bleeding using Tune ECU

[Scott Taunton]

Hello, Can I use Tune ECU to bleed the brakes and if so can someone give me a run-through of the process. Thanks very much.

Yes. You'll need to navigate to Tests and Adjustments. Here's a video on how to do it:

ABS BLEED will not work with TuneECU app on rockets 2.5

Any particular reason why? Works on my other ABS Triumphs.

UPDATE: When confused (like I usually am) I consulted the work shop manual and found on page 1218 the procedure for dealing with installation of the ABS modulator. The important steps are these:

1. Position the ABS modulator onto its bracket. Fit the washers and tighten the new fixings to 9 Nm.
2. Fit the anti-rotation moulding and tighten the new fixings to 5 Nm.
3. Incorporating new sealing washers to either side of the unions, fit the brake lines to the ABS modulator as noted for removal. Tighten the brake line unions to 25 Nm.
4. Attach the fuel tank electrical connector to the anti-rotation moulding.
5. Connect the ABS modulator multiplug (see ABS Electrical Connectors).
6. Back bleed the front brake master cylinder (see Master Cylinder Back Bleed in Bleedingthe Front Brakes).
7. Front Brake Caliper - Installation
8. Bleed the front brakes (see Bleeding the Front Brakes).
9. Rear Brake Caliper - Installation
10. Back bleed the rear brake master cylinder (see Master Cylinder Back Bleed in Bleedingthe Rear Brake).
11. Bleed the rear brakes (see Bleeding the Rear Brake).
12. Check the front and rear brakes for correct operation and fluid leaks. Rectify asnecessary.

Since the system is "integrated" apparently the ABS is purged with these brake bleeding procedures and the modulator does NOT require a seperate bleeding like other ABS systems Triumph uses. Interesting.

The brakes are not integrated. You seem to have a mental block about that. The function of the Hill Hold is "integrated" only if the rear brake has been applied when the front brake activates the function. If you didn't apply any rear brake, nothing happens to the rear. It only traps any pressure you applied, not linked or integrated at all.

The procedure you show is only for replacing the ABS module with another. As the system will be opened up. Yeah, I've had that done. It's not part of regular service.

I'm curious about your view of "integrated" since the front brake lever applies pressure to the rear caliper? I'm using the term as a broadly based engineering concept, perhaps a better term would be combined braking system:
Web definition:
Motorcycle integrated brakes, often referred to as Combined Braking Systems (CBS) or Linked Braking Systems (LBS), link the front and rear brakes together so that applying one lever activates both. This improves braking efficiency and stability by distributing braking force between the front and rear wheels. CBS can enhance braking performance and reduce skidding or loss of control in emergency situations.

Since the front and rear brake hydrualic lines are both routed to the same ABS modulator, they are somewhat "linked" in that they both end at one unit.

One final note the last time I activated the Hill Hold, both my feet were on the ground (if memory serves), meaning the rear brake pedal was not applied when stopped. It's an interesting point I'll verify this morning with today's ride.

The procedure is for bleeding the brakes through the ABS modulator, it's the same procedure whether you replace the ABS modulator or not. The only delta might be back bleeding if the system hasn't been opened.

As to Hill Hold, that actuates when the FRONT lever is squeezed REGARDLESS of rear brake pedal action. I actuated it 3 times today, got the dash indicator saying is was active all 3 times (it was, the rear brake did engage) the first time with the rear brake pedal used and in the last two instances I had both feet on the ground and ONLY used the front lever to light the indicator and the rear caliper did engage. So if "integrated" is bothering you, maybe we just call it "brake magic" and that'll suffice.
