Right that's me a qualified mechanic now. Master Tech within the month

Have now completed the removal, cleaning, copper greasing and refitting of the recently fitted front Brembo pads.

mpirie and others were right, provided you've got the correct tools and listen to what you're being told, this is a truly straightforward (but surprisingly satisfying) job to do and as has been said, you know exactly what's been done... I won't say 'that it's been done right' just yet, ahem

No brake fluid overflow, the front passenger side brake sensor wire simply clipped out and in via plier pressure on the plastic plug, nothing seized/ wouldn't come out, no danger presented from the caliper springs, just an A,B,C process.

Don't know what others do but to try and eradicate squeal and avoid re-work on this, I truly caked (painted) copper grease thickly on every bit of the Brembo pad, including all edges and the only part I left free of grease was the pad face that comes into contact with the discs under braking. I also got inside the caliper (which I didn't remove from the vehicle and cleaned that recess out with a stiff brush and brake cleaner and I actually greased the 2 piston faces inside each caliper too before re-fitting the newly greased brake pads.

No squeals, the brakes feel a little less metal on metal when applied and the calipers don't actually feel as hot as they did after a drive, although that might be in my head.

Time will tell but so far so good, touch wood

I've got the front discs and pads to replace ok mine, so now you're fully time served, could you do mine?

The squeal is back!

Just a little for now but creeping back nevertheless.

It only seems to come on after 3 or 4 minutes normal driving.

The first indication of it's return was a couple of days ago after having stopped at traffic lights in warm weather (over 20 degrees C outside) then when setting off and driving up a hill and turning the steering wheel slightly to the left, the squeak/ squeal came from the front passenger wheel area although not under braking.

It hasn't made that left steering turn squeal since but both front wheels are very lightly, intermittently squealing/squeaking under braking when the car is at operating temperature and has been driven for several minutes.

Also noticed last week a few days after greasing the pads that when reversing slowing and applying the foot brake there is an intermittent squeak/ squeal, apparently from the rear wheel (I've not re-greased the rear pads yet).

Don't get me wrong, the noises are nowhere near as frequent or loud as they were before. In fact it's negligible but just a wee bit frustrating. In saying that, we have a neighbour with a new - prancing horses badged - car and the constant brake squeal from that is excruciatingly loud and painful to listen to.

The RR failed it's MOT on the EPB sticking a few months ago and the remedy was to 'strip back and clean' the brake shoes at one hours labour. Whenever I drive the car, I always apply neutral and the EPB when stationary. I'm wondering if this squeal could be EPB related?

It could be the brake pad composition (Brembo pads all round). As an experiment, at the point of cleaning and re-greasing the front brakes/ pads, I completely cleaned the inner areas of the alloy wheels before replacing them and I haven't cleaned them for 2 weeks. They are now caked in brake dust.

I'd be interested to know how many members have used Brembo pads on the RR and whether they've noticed any brake squeal?

This is not the end of the world, I'm just curious.

Brake pad type and theories aside, I'm also trying to make sure I'm not missing anything else obvious. Any thoughts welcome.

Thanks in advance.

I'd like to think I didn't, but as you can see from the rest of this post, all it needs is a minimum of tools and a level of confidence to do a lot of DIY mechanics and i'd encourage anyone to have a go.

But if I did miss it....

Squeal is intermittently back!

Not coming on when brakes applied, so far, braking actually stops the squeal.

Seems to come on front wheels at about 30mph, usually after having set off from stop or slow speed. First noticed it this time when setting off and steering slightly left.

Strangely car wheels not been cleaned for a few weeks and I always wonder if a build up of dust from dirtier wheels brings it on!

Check its not the rears binding...... Can sound like the fronts depending on which way the wind is blowing

Mine are droning at slow speed at the moment, cant really be bothered to do them at the moment as they will need changing soon in any case. There is nothing that can't be fixed with a hammer😜😜

All new calipers discs and pads on the rear too though... Will check

Was informed by a listener that the squeal (worsening IMO & at times embarrassingly loud) has definitely maybe been coming from the front driver's side wheel.

So I've this week inspected the suspension arms, joints/ bushings on both front axles and they didn't look expired. Lubricated them all anyway to determine, shorter term at least,if they might be the cause of the wheelbarrow noise type squeak/ squeal... and it made no difference at all!

So, off with the wheels again and for the 2nd time in 2 months, out with the Brembo pads for a thorough stiff brush/ clean of the inside of the calipers and pads (surprising amount of accumulated dust I have to say), before filing down/ rounding off the squared/ sharper looking pad edges, finally, yet again thoroughly copper greasing the caliper piston faces and pads (not the braking surfaces!)...

Now also exploring caliper refurb, just in case.


And we wait... Shhhhhhh...

squeak,squeak,squeak......................

Well... Been raining and damp but after a wee bit driving today including on warmed up dry roads, nothing from the driver's side yet and it all does appear more velvet like down there again , ahem.

But... the front passenger side is still intermittently giving off cheeky wee squeaks!

So, front pass wheel will be off and will get same treatment as the the driver's side...

Can't wait til it's banished as the weather is closing in and it's getting cold driving around with the windows down all the time!

As an aside, assuming this is caliper/ pad related, is there a view as to how often brake calipers and pads should be cleaned and greased because although it can be done in less time than it takes to clean the car, once every 2 months seems ridiculous to me, although I've just read from some performance techie mechanic that it's an often overlooked safety shortcoming and should very much be done regularly?

here's a thought ryan, how about directing a pressure washer at the calliper/brakes to get rid of any brake dust or crud.. ... - .- -.
