Front Brake Caliper - 86 Turbo

[422hp944]

Hi guys - Been a while since I've been on here. My brother has an 86 turbo ( I repainted it for him a few months back - will post pics on another thread ). Anyway, he just rang me say it failed the NCT test ( Mot ) on a seized front left brake caliper.....Has anyone got a good used unit they want to sell? Or maybe steer me in the direction of locating one.... SH parts supplies are pretty non existent for 944s here....Cheers

Hi John

Can't help with replacement part except to say that they come up on eBay now and then but will say that a seized caliper isn't the end of the world. Mine (also 86) have seized in the past (about 10 years ago)but a quick strip down and clean soon had them back to good....didn't need to replace any parts either.

Hi Peter - Last time I was on here your project was on hold, Great to see you have the beast re-awakened!

That's good info regards stripping and cleaning, will pass it on....Cheers!

Is it actually a piston seized in a bore or just corrosion between the spring plates and caliper? In this case it's a common fault that in most cases can be easily rectified without replacing the caliper.

Not 100% sure Rob, Will have to investigate further......Might get lucky and be able to rectify as you say....cheers

Be aware that MY86 Turbo calipers are different from MY87 onwards calipers, although visually similar. Buy a pair, or be certain that it is a model year 86 part. Model year and year of production/registration aren't the same, so it needs to be a 23mm offset car. If it has 52mm offset wheels then its an 87, irrespective of whether it was built and registered in 1986.

Piston sizes are different so this is relevant if youre rebuilding too.

Not quite right Simon, all non-MO30 brembo front calipers are interchangeable across late and early offset spindles (I have tried them so can confirm this is correct). I don't know about the piston sizes though as I've not measure them, but then I wouldn't worry about this as long as they're replaced in matching pairs.

Or or just have them rebuilt, Eldavo had a set of MO30 calipers refurbed by a company he rates earlier this year but I've forgotten who they were sorry!..

Just to update on the Calipers...He got the front pair re-furbed for €420.00 the pair which was a cracking price. Thanks for everyones input...cheers

Is it ?

Think so??!!,.. got quotes from UK companies wanting that for each one!... Stoptec in Co. Monaghan, Ireland done the re-furb.

Absolutely correct. THE reason that I have mentioned it is because they all fit and appear similar, but the 1986 model year calipers have different piston diameters offering differing braking effort as a result.

If 1987>s didn't fit then I wouldn't have needed to warn him would I, as they wouldn't have fitted?

 

[944 man]

I believe that I clearly advised to buy and fit a pair where provenance was unknown, too.
