I'm attending a track day at Bruntingthorpe in a couple of weeks so thought i ought to replace my front discs which are pretty worn and have been doing some funny things recently. I bought a set from Brakes International and set about the task on Friday evening.

Took about an hour and a half to do both sides and was very straight forward. Excluding wheel nuts, you only have to undo a total of 6 bolts and screws per side. However, one piece of advice to anyone planning to do this job themselves. Do not attempt this job without an impact driver. You will not be able to undo the screws that locate the disc without one. I bought one in advance (only cost about

 

How much were the disks? Are they race items or fast road.

My car has about 35k on the clock and the front disks have a little rim on the side. The car will only be a weekend driver but I plan a nurburgring trip when it re-opens next year. It will probably be a good idea to get them done before then.

Did you replace the pads as well as the disks?

 

i replaced the discs with standard items which cost

 

Impact driver or drill the screws out, alternatively copper slip on them when they are installed, they are only locating screws and only hold the disc in place when you take the wheel off.

 

based on my experience, with an impact driver you won't have to drill them out. As you say, once you've got them undone once, a little copperslip will ease disassembly next time.

 

Or with a drill, you don't have to go out and buy an impact driver...

 

Cheers for the tip, will be adding one to my tool collection!

RE the 6 bolts though - should you be using a torque wrench to do them back up? I always tend to overtighten everything...!

 

or you spend

 

of the 6 fixings, 2 are screws that you would struggle to overtighten. 2 more bolts hold the caliper in place that you should really torque but in reality i don't. the other 2 bolts hold the torque plate in place and that does need to be really tightly bolted on. In theory you should torque them up correctly, but in reallity you would struggle to overtighten these bolts unless you have a monster extension on you socket or you lift weights for a living!

 

Oooh, I like the thought of converting hammering power into something more useful!
