Brake pad question

[peteA]

Not the usual which ones question...

I'm half way through changing the brakes on my Tamora and have some new carbon Lorraine pads to replace the current AP racing items. Upon removing the AP pads I noticed they have anti-squeal plates 'glued' to the back and there are non with the new CL pads.

I'm used to seeing plates between the piston and pad smothered in grease / copper slip but not 'glued' onto the back on the pad - is this normal?

If it is, and as I've removed them and will glue them to the CL pads but which glue should I use?

Thanks in advance

I use AP and copper slip them

Did you notice if the AP pads had a backing on them ie the anti-squeal plate?

Maybe a more general question - if anyone has replaced their brake pads, did you put them directly into the calipers or did you put anti-squeal plates in too?

I never suffered any brake squeal with the old set up so am happy to put back.

Cheers

When I had the fronts done on my Tamora, they didn't come with any anti-squeal plates, unless those were in the caliper already.

Your Tamora looks great by the way

See the picture of your old pads...the bits with the piston marks and copperslip...can you see that there is a backing material? This isn't present in the picture of your new pads. Presumably the new pads were fitted as they are with copper slip or maybe they removed them and refitted them to the new pads which is basically what I'm asking...?

I've fitted them loose at the moment to make sure there is space and there is it's just how to fit them permanently...do I glue the backing materials to my new pads? Using a glue...? Araldite maybe...?

I feel like I'm making a bit of a big deal of things but there's nowt more annoying than squealing brakes...well, there is but you know what I mean!

[Sevenman]

I am not sure there was backing material on the old pads, perhaps just where the grease has been squashed around by the pistons.

They were changed while at TVR Power, and I can't remember if there was anything swapped between the old and new pads. If you can't get an answer on the forum, give Power (or any of the TVR garages) a call and see if they can give a clear answer.

I like the look of the car (although want to retrim the interior), but it is not in my good books at the moment after a failed day at Millbrook. This is what happened, and this is the investigation so far.

Sorry to hear of your issues - hope it's ok and nothing serious.

My local is HHC so might give them a call and see what they do when replacing pads.

Cheers for your replies

Brummie can sort you new backing plates drop him a line ,

[portzi]

I made some pads from some stainless 0.9mm thick for my front pads,just a bit of cutting and bending in a vice,you will be surprised how easy it is , and a very satisfying job to do yourself.. Hope you get sorted soon

the pads didn't have any anti squeal. I had them out yesterday F&R to check for wear and re copper slipped them without. Squeal shims

[peteA]

I removed the anti-squeal plates (if that's what they are?) from the back of my old AP pads. They were glued to the back of the pad which is what is confusing me as I haven't come across this before?



The plates are flat with nothing to secure them in place other than the pins unlike portzi's items with the clip (they look good by the way). My thoughts are to re-use the AP anti-squeal plates on my new Carbon Lorraine pads but just wondering how to do it...



Do I...

- Put the plates in and smear both sides in copper slip and simply allow them to move about secured only by the pins
- Glue them to the new CL pads as they were to the AP pads and apply copper slip to the surface that contacts the pistons
- Not fit them at all and simply apply copper slip directly to the face of the pad as Buzz seems to have? Buzz, I assume your car doesn't suffer from brake squeal?

Thanks again guys.

Hi Pete , thanks for the compliments on the pads. The original AP pads had the shims glued then? I would be tempted to solely use the location pins and copper slip on the front and backs of the shims. If you get break squeel still then l think using adhesion is your next option. If you glue them first and still get squeel your out of options for the shim removal?

Its better to fit the pads with as few components as possible for outright performance, all those plates and shims need compressing before pad contact to the disc is achieved.
However if it does squeal (vibrate) then dampening this can be done by adding noise reduction shims, i can supply you these in the form of 3M self adhesive pads.

Cheers Paul.

Thanks guys

Agreed - I'll put them in covered in copper slip and see how it goes.

Any problems I'll give Brummie a shout for some adhesive items.

Paul, speaking of pads...and things...what options have you for the front of my tam?

Rc5+ is the most versatile, perhaps our New 330R (330mm)conversion too!?

Looks impressive. I assume you need a different depth spacer for the calliper and the appropriate length bolts?

Yes, all supplied as a complete kit.

ETA they dont go under 16" spiders, we tried...

Paul is bang on the money. I have 16 inch spiders on my chim, and the standard 305 ? Diameter disc and AP caliper are a very snug fit, as your talking literally 2-3 mm clearance from caliper to inner wheel. So with a bigger break set up there's no chance of fitment, bigger wheels are need !!

Hi Paul do you have an upgrade rear disc set for my T 350 please as I already have a front 330 upgrade?

Thanks Don
