Trying to remove discs

[edgeydt50]

My brakes have never felt that great since buying the car so ordered a new set of brembo discs and pads.
Im having a nightmare trying to remover the torx screws that hold the discs on. Its now a case that they are almost knackered. Have used penetrating fluid and had someone step on the pedal to keep everything still. Is there something else i can do to get them to budge.

When having a look i noticed that the disc looks a lot more worn than the pads, there is noticeable groove on the inside pad. Im guessing this isnt meant to be there as the new pads are flat.

just drill them out, will take 10min tops

Could i drill it and then hammer in a T45/T50 bit?

 

[JamesBryan]

Just drill it out completely.

 

[edgeydt50]

sorry new to this. So the drive of the drill will pull it out or ill have to re-thred it. Cheers

 

[JamesBryan]

Use a slightly smaller drill bit and it won't damage the threads.

Completely drill the bolt out with a slightly smaller drill bit and then re-tap it if you want to put the retaining bolts back.

From what i have read they are just locating screws and arent 100% needed. Should have looked into this earlier rather than cursing as i would have taken a drill to it straight away. cheers for the help!

I always use an impact driver with a hammer to get them out. Never had an issue.

As above , impact driver normally sorts them

 

[edgeydt50]

should have tried that first. Ill do that on the other side when i get a chance to give it a second go!

 

[George@RTR_Parts]

if you don't have one a punch and hammer does similar thing , shocks and turns. But I'd advise the impact driver tbh if you have one/can lend one

 

[JamesBryan]

Never actually used an impact driver, I take it you just hit the end with a hammer and it turns the head with a quick shock?

Yeep!

 

[JamesBryan]

I think i need me one of them!

Chizel it round or weld a nut on like i had to.

Try and drip some.brake fluid behind the nut to free it up a bit and wait for it to soak in. If u have any spare of course.

 

[George@RTR_Parts]

Don't worry about making a mess of the old torx bolts when removing them Chris. There is a couple of new ones in the box with the Brembo discs mate

 

[edgeydt50]

nice one ill get a drill on the screwed up ones and have an impact driver which i will use for the other side.

I found that when drilling them out, the drill loosens them up enough to pull them out.

Drilling with a 8mm drill bit will just shatter the head off releaving force on the threads. You then remove the disk which is 7mm thick at that location and just unscrew the threaded part by hand (no more pressure from the threads and 7mm protusion to hold it). If threadlock was used (not a good idea) you can still fit a pair of pliers to unscrew.

This^^^^

Thats how i did mine.

If you're scrapping the discs anyway, get a grinder out and take the head off. Dont worry about the disc.

Been there and done that

You love that grinder!

Won't be able to do it much quicker!
