Ok, so just driven to the local village to get some lunch. On the way there I had to perform an emergency stop from 60mph (probably a bit higher). The brakes worked fine, as expected and I managed to drive off fine after that. The next time I used the brakes, a mile or so further on I noticed that the front right brake feels different.

It's almost like the disc is bent, it's causing the corner to vibrate heavily, which changes frequency depending on speed. Braking is now biased to the left, although the right isn't really much worse in terms of braking effort. The pedal bounces a bit too like the piston in the calliper is being smashed in every turn of the disc.

It sounds pretty rough too.

When the brakes are off, the car is as normal.

Car in question is a 2001 ford focus 1.6 petrol with 135k on the clock.

Thoughts?
 
Cheers Matt - I'll fetch the pads out when I get home and inspect/post photos if i need further help.
 
Just went to Euro Car Parts to enquire how much a pair of discs and set of front pads would be for my car.

Using the Crazy 25 code, which should only work a the weekend, I managed to get the lot delivered next day for £45. Get in!

£45 for discs and pads?! BARGAIN!

Tell me about it!

Should be here tomorrow.

Pads I have done before. Is it the case that I have to remove the calliper mounting and the disc should then just pull off, albeit with a little leverage if necessary?
 
The pads are due to be renewed soon anyway, and for a extra £20 for rotors, I thought **** it, may as well.

As mentioned in another thread, my brother will be stripping this car for parts for his own soon, and one thing he needs is brakes - I'd be happier him driving about knowing the parts he's taking are in good working order.

Sigma - if it is a sticky caliper piston, is it the case that I need to get the caliper off and push the piston back in manually?
 
Technically you should use a "Calliper rewind" tool, but I've done it before with a medium sized vice and it worked eventually.

Replacing the discs is pretty straight forward - there should be 2 bolts on the back of the calliper, unscrew them with a socket wrench or a spanner (Might need a tap with a hammer to start them off). Then lift the calliper off and put it to one side. Support it with something, do NOT let it hang on the brake line.

Tip to get the disc off, there might be a hole on the disk that one of the calliper nuts will screw into - don't know if this is standard or not, but my mx6 had it - this will leaver the disc off.

Then reverse the procedure to reinstall, putting the new pads in the calliper as you install it.
