Hi,

I put some new pads in today (front) and not sure it right.

Taken it for a quick run and it brakes well but on returning home I noticed a lot of heat and the disks were extremely hot to touch.

It had Halfords pads in before, had 4mm of meat on the but braking was terrible and was getting a bit of squeal.

I fitted Delphi Lockheed recommended by my local auto store.

I did notice they were a slightly different shape to the Halfords ones. The dealer checked they were correct on ordering and on delivery and they slot perfectly into the caliper so fairly sure they are correct.

Is the heat normal after new pads?

not normal. Depends if you gave the breaks a good work out or not.

 But it will bind if the caliper sliders are sticking.

 Jack the car and spin the affected wheel. It should spin freely without any rubbing from the pads, although some "shooshing" is not unusual.

If the wheel binds, and it sounds like it is, then you need to service the calipers. Make sure the piston retracts/moves as it should and the piston seals are ok. If the rubber boot splits you can get corrosion on the piston and this can drag/stick on the seals.

Check the sliders move freely also.

You probably would have noticed these when fitting pads though.

But jack and spin the wheels as a start off and see if they bind.

Thanks,

Sliders were ok. Struggled to get the piston back in so bought a 4" G-clamp. went in easy enough after that.  Seals seems ok, didn't notice any damage.

Span the disks after i'd refitted. Seems to catch slightly in a certain spot. Not enough to stop it but enough to make a slight rubbing noise.

I did a mile but was up to nsl speeds doing full and hard breaking.

I'll keep an eye on it, thanks for the info

Copper slip is the answer!!!!!

Thanks Andy,


Been out again and seems fine now. I think it was just the different design of pad bedding in.

was there a strong burning smell?

[Black Knight]

Yeah, first time out, didn't notice 2nd time.
