 Hyundai i10 - 12 1.0 Brake master cylinder problem - percy
Hi, I'd be grateful for any advice on the brake problem with this 2012 20,000 mile i10.
This car belongs to a neighbour, was serviced by Hyundai while under warranty and is now regularly serviced by a mobile mechanic.
The initial problem was the front o/s caliper showing signs of binding.
The mechanic freed up the caliper easily, then the decision was taken to put new pads in.
The o/s slave cylinder pushed back under finger pressure, however the n/s cylinder needed gentle assistance with a g clamp. New pads were inserted on both sides, brake pedal depressed and the problems started.
I've lost a bit of the story here, but essentially the n/s cannot be bled, the pedal is floppy and there is much head scratching. The mechanic talked to a local (non Hyundai) garage that were having a similar problem with an i10 and had installed a new £300 master cylinder to no avail. My neighbour purchased a second hand m/c from eBay which also doesn't provide a cure.
An attempt was made to dismantle the original m/c see how it functioned and what might have failed, but it doesn't appear to dismantle easily. There is very little information available on the braking system.
Has anybody come across this problem/or can throw any light on it?
Many thanks in advance.
