Brake Overhaul Guide

Thanks to Maranellohouse for allowing us to use this:

Brake pads arrived today and boy am I pleased (Ferodo Pads FDB451 and FDB998) fronts were £28 and the rears were £22, and they are made by Ferodo, a make I've used for years on all different cars.

Fitting the fronts was very simple. Simply pull out the 2 retaining pins, making sure the spring plate doesn't take off across the floor, with the old pads still in place use a decent flat end screwdriver to prise the pistons in using the old pads as leverage so you don't do any damage to the pistons. If they have been pushed in fully the new pads will slide straight in.

Rear pads are just as easy to fit, the only difference being they are held in with strong spring that clips in at the top. The spring is hinged onto the caliper at the bottom and more than likely will have siezed so spray a good bit of WD40 around it and leave it a while before trying to free it. Getting the pads out is exactly the same way as the fronts are done.

The rear discs have to be taken off to get at the shoes. The caliper has to be removed first but it's only a case of removing 2 19mm bolts to get the caliper out. The disc is held on with 2 13mm bolts. Once they are out it's a bit of tapping with a hammer to get the disc to release... The shoes are held on with 2 retaining clips and 2 springs top and bottom. There's an adjusting wheel at the bottom of the shoes to. This will fall out when you have the retaining springs off. I'm holding it on in the photo below so you can see it... Oh nearly forgot, slacken off the handbrake cable as well. It has to be done from under the car and is 2 10mm nuts.

Re-fitting is just the reverse of taking things off. Once the discs are back on you can adjust the shoes via a hole in the disc.

Now, Maserati were looking £137 for a set and there's no way, once you see them, that you will ever figure out how they can charge so much for a set. They are smaller than a Fiat Uno's for dear sake. I wasn't for paying that so off I went with a shoe in hand to my local motor factors to see if I could match them . It took me all of 5 minutes to match them. £22 all in. The ones I bought needed very slight modification to be made fit. I'm not going to post up what vehicle the shoes are the same as because I don't want to be held responsible if you buy the same ones and they don't work, however if you own a 3200 and you want to try the shoes yourself email me and I'll let you know what shoes they are.

After I got the brakes all on it was the first chance I got to try the car after fitting the lambda sensors. "WOW" is all I can say, the car had clearly not been running right since I bought it, and I'd thought it was pretty quick then. It now runs silky smooth and the power delivery is fierce. This is a car that I could lose my license over, you just don't realise how fast your traveling and have to keep one eye on the speedo most of the time. I like this car, a lot.

Another angle I looked at was to get the original shoes re-lined. I used the The Belfast Brake Company and the results you can see for themselves. A lot cheaper than having to buy a new set! Since I have the other shoes on now, I'll keep these ones good.

Really helpful stuff Conaero.

One other tip, which may apply here (I haven't changed the pads on the Maser but have changed on other motors), is to be careful as you push the pistons back in that you don't overflow the master cylinder and spill brake fluid out into the engine bay.

Cheers

Good point, I will add my two penethworth:

Make sure that the pad guides are clean, and rust free. Pads need to drop in and not need to be tapped in. It is standard procedure to file the edges of the pads to make them fit. Blob of Copper Grease on the back of the pad always aids non squeak, and keep the grease of the friction material.

Using new pads on old discs will result in the pad shaping to the disc contour, so if you discs are passed it, replace them. Vice versa, don't use old pads with new discs as again, the new disc will take the contour of your last disc, transferred from you pads.

good guide. my penethwoth:
apply SMALL amount of copper grease to the retaining pins. Stops them seizing on and makes next pad change easier. I havent changed the pads on my 3200 yet but I think it will be soon along with disks. On motorbikes, I always peal the dust seal off and make sure there is no corrosion on the pistons. IT would need clean around the pistons BEFORE they are pushed back in as otherwise they could damaged the seal. I always put a SMALL amount of ACF 50 grease to prevent corrosion and ease the retraction of the pistons. This grease is brilliant stuff as is the ACF 50 spray. I use these on all exposed alloy castings to prevent corrosion from road salts and lasts for six months. The use it in aero wings to prevent corrosion so it must be good for our flying machines!

Cheers
bill

PS Also a bit of copper grease on the wheel bolts is good too

Hi Conaero,

Thanks for the guide. Do you happen to know whether the 3200 shoes are the same for the 4200? If they are then it would be good to know of alternatives to the OEM.

Thanks, Emtee.

Emtee, I was under the impression that the 3200/4200/GS have the same brakes all round including the handbrake system, but Mike Roberts pointed out to me recently, that the 3200 and GS share the same system for the handbrake but the 4200 is different.

Can anyone with a 4200 care to explain what the difference is or whether Mike has been sniffing the injector cleaner again?

...I have just checked on Eurospares and the early 4200 has a different part number from the 3200 for the rear shoes and a different drawing, so looks like Mike is correct, well, didn't doubt him it just seemed odd.

Thanks Conaero,

I think I must have been doing the same thing at the same time, but I've just been checking again on Eurospares as I got different groupings of part numbers?

3200, 3200AC and 4200 (including Spyder) to 2002 (to car ***. No. 7717) - Part number 388000111. (also mentions 170701 but I can't see how this relates to 388000111)
4200 (car *** No 7718 onwards), 2003 onwards (including Spyder) and Gransport - Part number 194876 (superceding 186575)

So the Gransport seems to take the same shoe as the later 4200's with the 3200's sharing with the early 4200's, which would seem to make sense from a chronological point of view?

So I wonder whether anyone has found an OEM alternative for later 4200's and Gransports?

Cheers, Emtee.

Just get them re lined, its easier.

I have contacted The Belfast Brake Company, to get a forum members price for the job, should here back today.

We have an old set of handbrake shoes that are doing the rounds, where you have those re lined and send you old shoes back.

Thanks Conaero,

Re-lining a spare set that fit post-2003 4200's would be a good solution, but being my daily driver I'm trying to avoid the down-time to take mine off for re-lining, especially as they've just failed on me :-(

Cheers, Emtee.

Just turned up, thanks to Jezza for suppling the old shoes, they are absolutely perfect, painted and stickered up with Lucas logos:

They are bonded with a much stronger glue than original, so they are less likely to de laminate, as what seems to happen a lot.

Will do, Loz if you can ask Grimaldi to put some shoes aside for us it would be appreciated. Mike Roberts is doing the same, but does them rarely.

My old set are going back for refurb and Jezza is having them.

Can I assume my Assetto Corsa front calipers are the same mechnical unit as all other 3200, GS and 4200?

Appears so, just painted red to make them stand out.

Like to know my options about refurb
