Willbof Posted August 30 Share Posted August 30 Coming towards the end of my restoration and I've got an issue with the brakes. New pads and discs fitted but when I turn right the abs kicks in and gets to lock the wheel up, quite scary! I've pulled the hub and sensor to take a look. Sensor looks fine but the hub has some weird marks on the abs ring. Assuming this is the issue I've ordered freshies but just wondering if anyone has seen such an issue? I'm not sure what cas causes the marks either 🤷🏻♂️ Car turns fine with abs disabled btw. Quote Link to comment Share on other sites More sharing options...
mr v6 Posted August 30 Share Posted August 30 I take it you've scanned it to verify you're on the right corner? Does look knackered that though. Quote Link to comment Share on other sites More sharing options...
Willbof Posted August 30 Author Share Posted August 30 Ye, zero codes though and drives normal when it's straight/gentle cornering. Just kicks in abs when I turn right Quote Link to comment Share on other sites More sharing options...
zeditis Posted August 30 Share Posted August 30 As far as I'm aware abs does not apply brakes but the stability control will. Quote Link to comment Share on other sites More sharing options...
Willbof Posted August 31 Author Share Posted August 31 Hmm, so do you know if the stability control works solely from the yaw sensor or would the wheel speed have an input? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted August 31 Share Posted August 31 What wheel is locking up on right turn? Is the wheel locking up without applying the brakes? All parts are in stock to fix this issue. Hubs, ABS sensors, yaw sensors. etc. etc. etc. Quote Link to comment Share on other sites More sharing options...

Stability control will be a constant calculation using yaw rate, steer angle and wheel speed. It will intervene if it detects oversteer or understeer by applying brakes and cutting engine power. Can't answer for specifics on zeds, but that's the general idea. Edited August 31 by Keith D Quote Link to comment Share on other sites More sharing options...
mr v6 Posted August 31 Share Posted August 31 I'd put it on a diagnostic tablet & graph all 4 corners on a screen, the graph will show you which (if any) are dropping out. My Launch does this, very handy indeed. Quote Link to comment Share on other sites More sharing options...

Hubs, ABS sensors, yaw sensors. etc. etc. etc. Front right when turning right is why I noticed, just took her for a spin and going round a roundabout it's grabbing what feels like both fronts. Switch tcs off and no issue. Both front hubs replaced. No abs warning or faults. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted September 5 Share Posted September 5 The traction control monitors wheel speed using sensors, which are integrated with the ABS sensors, so I would firstly be looking at that. Sensors, modules, and front hub bearing assemblies are always in stock. Failing that, I would be looking at the VDC If no cheap, quick fix can be found, then just run with the TCS off, as most of us do. Quote Link to comment Share on other sites More sharing options...
