c70 abs
would a faulty abs / stc control modul affect the feel of the brakes. ive aquired a c70 auto, full service history. off a friend which lost drive in the snow a few weeks ago, ive changed the fluid and seems ok on the short test drives ive done, but the stc lights flashing and the brake pedal seems a bit gritty and not excactly responsive, my micra and citroen has better biting brakes. any help would be greatly appreciatted.

found the problem, abs interrupter ring broken and i think it was stuck on the abs sensor, so im presuming the abs thought the wheel was stationary therefore the abs was coming in on that wheel making the pedal feel lumpy, and some horrible scraping noises.
now the brakes work ok but doesnt seem as sharp as my micra, acording to all the bills ive got the pads were changed around 5000 miles ago ( no idea on the make ) but looking at them they dont even look like theyve done 500 miles. so is there a softer pad available. geof |

Hi gnc
Others on here have posted in the past, that out of the two front pads that Mintex makes (for early V70s with 15 and 16 inch wheels), the MDB1984 are the soft ones. https://www.brakebook.com/bb/mintex/...onSearch.xhtml MDB1984 Brake Pad Set, disc brake Fitting Position: Front Axle; Brake System: 16" Brake System:Teves; Width [mm]:156.3; Height [mm]:58.3; Part number of recommended accessories:MBA1180; Thickness [mm]:19.5; Wear Warning Contact:not prepared for wear indicator MDB1614 Brake Pad Set, disc brake Fitting Position: Front Axle; Brake System: 15" Brake System:Teves; Width [mm]:156.3; Height [mm]:58.3; Part number of recommended accessories:MBA1180; Thickness [mm]:19.5; Wear Warning Contact: prepared for wear indicator Hope that helps, Steve

Hope you don't mind me jumping on your thread. I'm having a similar problem with my V70, no lights coming on but it feels like the abs is cutting in. It's making the horrible scraping noise on and off and your description of the pedal feeling gritty matches mine. Front drivers side ring is corroded and got a bit better when cleaned up a bit but still there. No codes stored so I think it is as you described and the car is getting the wrong signal for the wheel speed. Only thing that's a bit odd is sometimes I brake and it's not there at all but 90% of the time you can feel and hear it while braking.
Did you manage to change just the ring? 2 local garages are saying it will have to be a replacement cv joint at around £180 as the ring is welded to the end of the joint but the rings are available to buy on their own online so I'm a bit confused. Thanks

Hi Mike
Ring is not welded, it is a press fit, 99% sure. Steve

Thanks Steve, that's what I thought.
Maybe they are thinking it would be rust welded on and too much effort. I've ordered a replacement ring (£1.99 with a lifetime warranty!) and I'll give it a go.

Hi gnc,
99% sure it is fine to disconnect the power (3 lead) cable to the ABS module (at your own risk). The ABS light will come on. At least you wont have that noise. You will still get normal unassisted hydraulic braking, but obviously no ABS. When you reconnect the power to the module, the ABS light will clear. Steve

It'll still be assisted, but no ABS in the event of a skid.

Yes sorry, by unassisted I meant not ABS.
