Technical Just replaced the front disc and pads.

[Hellcat]

Wow what a job.

Luckily I had help as it's quite a big job. The discs as one of the blokes said are "bloody massive".. as are the calipers. To get the caliper hanger off the hub carrier you need a wierd looking socket (and a long breakers bar).. looks like the opposite of a torques bit.

After than you will most likely need a big hammer and a bar to prise the rusted on disc off the hub. Once that was done it was a simple job of cleaning the bits off with a wire brush, and re assembling with a healthy quantity of copper grease.

Didn't fancy paying for them to be fitted since it had already cost us £250 for the discs and pads - and that was with a healthy discount

i know the socket you mean, not sure of the name but i have some in my tool set just never needed them

what size are they then?

any pictures as i'm intreguid??

Ry

The actual setup wasn't really any different to the standard big fiat setup, just the componenets were a little different. In fact, the discs are just the same size as the 2 litre Tipo or Bravo/Marea.. 284x22

Think I've discovered that these sockets are called STAR sockets. Dunno how sizes work but we used the largest we had available.

 

[bulldog5046]

you want to try having a go with the brembo 305mm setup, now thats heavy!

Personally I use high temeprature moly grease. At hin smear is all that is required. Copper slip/grease has a good temperature rating but it's water resistance is poor compared to loy grease.

NOTE! Most of, if not all of these star bolts on the Croma are "stretch" bolts that Fiat say must be replaced and not used again.

Of course we all do...and use the approved torque figure too :devil:

The bolt pattern is called 'RIBE' if that helps. Vauxhall use it too, but then that's what the Croma is anyway. Many brake components are shared with the Signum, have a look here for comparison between models. HTH.

The one holding the brake caliper on wasn't a stretch bolt. But the head was a 'star' one. Different to a ribe bolt (male vs female)

Oh and the size might have been 305mm which is bigger than the 284mm on the top end Tipo/Marea. No wonder they looked HUGE!

Only on suspension parts if removed.

Have you used Fiat pads or from a factor?
I have just bought some Mintex pads but only one in the set has a wear sensor. I am told all after market sets only come with only one sensor.
Can anyone comment?

 

[Hellcat]

Only the nearside has a sensor. They were Fiat pads and discs.

£250.00 for front discs and pads!!!! With a Discount!!!

I paid £100.05 for pair of 305mm discs ( Lucas ) and £38.00 set of pads with sensor ( Lucas ) yesterday from the brakepartsuperstore.co.uk

Some saving!!

 

[Hellcat]

Yup.

OEM parts for warranty. Can't question the quality of the parts though. Painted on all the non-braking surfaces.

 

[FiatFleetFamily]

Even though the Croma has 3 companies that supply brake parts??

Lucas, Girling and ATE all fitted at factory for discs and pads.

 

[Granvilleb]

I have just replaced the front pads and as you said only the left side has a sensor. BUT the left side had about 4mm left and the right side was down to 1mm. This is the first time I have known a vehicle to only have one wear sensor. Who decides which side it should be on and why?
I got my pads from Surestart, the people who sell the windscreen wiper blades, £25.

'E' sockets

I'm looking to replace all discs and pads on my Croma. Fiat dealer wanted £450 to fit front discs and pads . Have a reliable local garage that will replace all pads and discs for about £80 (with me providing parts, my preference). Sounds like a good deal to me, but I just need to make sure I get the right parts.

My car is a 56-reg 2006 1.9D 16v Prestigio. Had a look on brakepartssuperstore, and they offer the following options for this model:

Rear pads - only one type
Rear discs - 279mm or 291.9mm
Front pads - ATE or Lucas/Girling
Front discs - 285mm or 305mm

Anyone know which parts I need, or how to find out? I can't think I could measure the disc diameter very accurately with the wheel in the way.

 

[Hellcat]

If it's the same as Bunny's Eleganza 1.9 16v multijet then it will use the larger 305mm discs.

305mm front & 292 mm rear on the 1.9 16V and 2.4 20V according to the Croma brochure. Front pads / calipers are TRW aka Lucas/Girling.

HTH.

Aha - looked on the ELearn CD (never thought about it before) and found out it needs 305mm on the front, 292mm on the back. Here are the full tables in case it's of use to anyone else.

Am I just being thick, or does it only allow about 2mm of wear (1mm per side)? Is this normal - it sounds very low to me. I've seen discs where the pads sit in a deep groove. Modern pads seem to eat discs.
