Brakes have grinding feel, not discs and pads, replaced abs pump?
I have a ford cougar 2000, over the past 2 yrs problems has got worse, felt like slight give in the peddle, grinding feel when pressin peddle, pads and discs are fine, abs light comes on after about half hour driving, and sometimes handbrake light, replaced abs pump, no change, previously taken to ford no compuetr errors when tested. AARRGGHH driving me nuts, any suggestions welcome
is the same before and after bleeding so dont think its air, hard to describe the feel of the peddle, could it be the sensors, what are symptoms of abs sensor problems
barkes are less effective and problem is more prononced at low speed
Answer:
If the sound comes from the back it's likely the cars had a new transverse brake pipe at tome time in it's life, and the new one isn't the right one, probably too big. This means pressure doesn't build properly and gets unevenly placed onto the pads, meaning you may have your pads only pressing in at one side. This would explain the slight loss of braking, and the soft feel of the peddle. To be honest though it's only really theoretical but it's worth checking this out. Technically the symptoms you listed do match in to this type of fault, but fitting the wrong pipe is not only very difficult but would require a real dunderhead of a mechanic to do without noticing!!

Scratched Xbox 360 Discs and Laser Burn
The Xbox 360 games console has developed a bad reputation for damaging game discs when the machine is moved or subjected to strong vibrations when it is switched on. In this article we take a look at what effect this has on your Xbox 360 game disc and what can be done to repair it if it becomes damaged in this way.
How Do Xbox 360 Discs Become Damaged?
There are several ways your Xbox 360 game disc can become damaged. Firstly, most discs develop light surface marks overtime when they are repeatedly taken in and out of a game case. This type of damage very rarely causes any playback problems.
Secondly, if a game is not properly cared for then it may develop heavier scratches, some of which may even prevent the disc from playing. Last but not least your disc may become scratched should you accidently move your Xbox 360 console when it is switched on. This is commonly referred to as ‘Laser Burn' by gamers.
What Is Laser Burn?
The term ‘laser burn' is actually very misleading. If you knock over your Xbox 360 console while playinga game, your laser doesn't actually ‘burn' the disc. Instead the lens of your laser comes into physical contact with the disc as it is spinning and creates a circular scratch around the entire disc. Therefore the damage caused is actually a radial or circular scratch rather than genuine laser burn which is completely different.
Can Scratched Discs Be Repaired?
Yes. Xbox 360 discs can be professionally repaired with a disc repair machine, regardless of whether they have light surface marks or heavy circular scratches. The machines work by grinding away a very precise amount of the shiny side of your Xbox 360 disc. This will not damage your Xbox 360 game as your discs data layer is covered by a thick layer of polycarbonate.
Ironically, the shiny polycarbonate is intended to protect your discs data but when it becomes scratched it can actually prevent playback. Therefore by removing any scratches from this layer you also remove any obstacles blocking the laser from reading the data.
Polishing The Disc
Once enough of the polycarbonate layer has been removed your disc will be polished. This stage is very important as only grinding the disc, while typically addressing playback problems, leaves the disc looking in worse condition than it started, with heavy radial and/or sanding marks.
Some low cost disc repair solutions either clean or grind the disc, they rarely do both and when they do the results are often unimpressive. The calibre of machine needed to perform high quality disc repairs can cost hundreds, if not thousands of pounds to buy.
Therefore if you only have a few discs to repair at a time, it may be worth using a professional disc repair service. That way you can be assured of getting a high quality, like new finish for your favourite video game every time.
