New pads, grinding noise on acceleration and decel

Hi Everyone,

 

So..... i've got this noise lol.

Had new pads fitted and after driving for about 5-10mins i'm getting an alarming grinding noise under acceleration (past 20 mph) and under deceleration.

 

I'm thinking its something to do with the pads, or a drive belt rubbing somewhere as the pads were done and the belts were inspected, yesterday.

 

Maybe i shouldn't use halfords autocentre lol. Their brakes4life offer was very tempting! :(

 

Thanks guys.

maybe something stuck in the pad face.... :shrug:

 

That's sort of what im thinking, dust/foreign matter in the way, getting hot and causing the noise possibly ?

 

incorrectly fitted shims? :shrug:

 

Another thing im thinking lol. Or they are possibly not there !?

 

This is annoying, only had the zed for a week! :(

The sound doesn't happen when applying the brakes, super quiet operation etc.

 

Are there heat shields/ disc shields on the front discs??

Maybe they dislodged it??

 

The sound is similar to when you have pads with no meat, squeeze the brakes and get the awful scraping noise lol!

PSssst Vik is a ladyyyyyyyyyyyyy..... ;)

 

 

lol i have friends, who are women, and i call them mate, buddy etc ;)

 

 

Do they need bleeding?

 

The brake fluid was changed, but i can't imagine the brakes working properly if there was air in the system. The OSF brake doesn't appear to be sticking either.

Go back and ask them if shims were re-fitted :thumbs:

 

I'll ring them first thing in the morning, thanks for the advice mate :)

 

:lol::lol: some would query the 'lady' bit - entirely female...all woman... but a lady?!!

Don't worry McTwist - am totally used to it :thumbs:

:) well at least now you have your definitive answer from Alex instead of us lot making wild stabs in the dark ;):thumbs:

 

All the help has been great, also confirming some of my suspicions. I will mention the shims to them as you recommended too, because its very likely that the shims could have been neglected completely.

 

 

Sounds like the back plate is touching the rotor :thumbs:

 

Take it back, it is only a 2 minute fix :thumbs:

 

Alex. :)

 

Cheers Zman, really appreciate the advice.

p.s ill be in touch with you later this week to confirm my order, minus the plugs if thats ok :)

It's only a two minute fix if you know what you are looking for. Saying that, if the Halfords monkeys had known what to look for, this issue wouldn't have appeared in the first place, no?

Could It be because you took it to Halfords?

You're like the 6th and 7th people to tell me that :-/. Initially i thought that getting free pads, for ever and ever, as often as i need them, would be a good idea for a 300hp monster lol!

Maybe not a good idea taking a Zed to an autocentre, more suited for corsas and focuses i reckon ??

 

Good news though, exactly as the Zman predicted, was the backing plate touching the rotor :thumbs:

Glad you got it sorted :thumbs:

 

When it comes to cars.....find yourself an independant you trust and take your car there.

+1 You don't want a 16 year old apprentice from Halfrauds messing with your Zed! leave it to the specialist! There are plenty of Jap car specialists out there, who are passionate about them, you always know your in safe hands.

 

The only thing I buy from Halfrauds is cleaning products, tools and bulbs!

Thats a fair point, i've always looked for independent specialists for any of my cars in the past.

The zed, being the best car i've ever owned, should be no exception for that.

It was the convenience aspect to, drop the car off and only a 10 min walk to work.

I initially spoke to a few people about Halfords Autocentres (prev. Nationwide autocentres) and were told they dont hire anybody from the halfords branches, just their own trained mechanics, no pubescent trainees.

 

Sums it up really, two attempts to get brake pads right... 'nuff said :-/

It could be a genuine mistake, but changing pads should be standard procedure for a place like that. Do you know what pads they use?

 

There are a couple of Jap specialists near me in Camberley that i know of, one in fleet (i forget the name) and one in Normandy, Eurospec, which i have used before for a clutch change on a previous Zed. If you ever need an parts, speak to the traders on hear ZMANALEX for example has pretty much everything. CS also sell a lot of parts, i recently bought my discs, pads and brake lines all round from them. For all your exhaust needs, speak to TARMAC. :thumbs:

No im afraid i don't i would like them to be blueprint, ferrodo or mintex OE items, but i doubt it. They are bright red! lol

 

Thanks for the recommendations, a few other peeps have mentioned the place in fleet.

Got to order my gearbox oil from the Zman :)
