Hi all
Got a new issue with the gts 300.
When I turn on and begin to move there is significant pressure on both brake leavers.As soon as you pull the leaver the pressure goes and brakes seem to work as normal.
Anyone come across this before.

When was the last time you changed the brake fluid?

there's been a few reports like that here, some have just gone away (sometimes with new fluid and bleed) and some had to replace the abs unit. An interesting experiment would be to remove the fuse for the abs and go for a ride

Not sure when brake fluid was last changed.Last service was a year ago ,but can't remember if fluid was changed .I will change and see if issue resolved.
The odd thing is brakes seem to work fine, just leavers are very stiff on first moving off.

If I remove abs fuse will brakes still be safe?

I've noticed a few posts regarding brake issues,I was wandering if this was an inherent gts issue?

Yes. Deliberate safety design. Brakes don't need a working battery etc.

Asked because there where multiple safety recalls because of brake issues for several years of production (including Production in late 2018).

Please double-check:
- https://static.nhtsa.gov/odi/rcl/2019/RCLRPT-19V826-7351.PDF (only one example of a recall)
- check VIN with http://recall.piaggiogroup.com/default.aspx?BRAND=&LANG=EN
Note: Even if the Piaggio database does not show a recall for your VIN, that does not mean there is no recall. Only Piaggio or a dealer can confirm/exclude a recall based on the VIN.
- Call Vespa direct, and ask if your VIN is affected (and if yes if recall is done)
https://www.vespa.com/us_EN/customer-care/
- And/or contact dealer to check your VIN.

I had a similar problem with my front brake. Started out like yours but eventually the brake lever could not be pulled in at all. Very dangerous.

It was the ABS unit. Dealer replaced it even though it was out of warranty.

Piaggio is well of aware of faulty ABS units and brake issues.

Contacted Piaggio .No recall on my bike.Although it has been an issue on some models.Have bled all brakes no improvement.Looking like it's the ABS unit.Not sure if that's something I could change.Sounds like a dealer issue that will be expensive….

Yes, it is. Be ready. The dealer quoted me about $1200-1500 (I forget) just for the ABS unit.
