Front brake upgrade
tomgregory2000 - 15/7/09 at 09:05 AM

I have been thinking about upgrading my front calipers to some 4 pots,
Now my question is has anybody used the pug 406 coupe brembo calipers on sierra uprights?
As i have found a pair for not much money
I guess it will need a bracket to adapt the fixing holes which is not a problem for me.
Or do i go down the normal route of getting some wilwoods?

Any advice welcome
(just trying to save some money, and i know brakes are not something you should skimp on but saving £100 plus is alot of money)

if you engineer it youre not skimping, the brembos are perfectly good calipers (arguably better then the wilwoods)

First of all you need to find out if they are radial or lug mounted and then look into whats required to get them mounted up.

One must ask first, why you wish to upgrade? have a look at the piston areas and see if youll gain anything.

think i'd go down the wilwood route personally.

There are a few reasons, one of my current problems is that one of the sierra calipers is getting a bit sticky and of course looks but also on the nearside the wing stay is very close to the back of the caliper and that is with new pads fitted so as they wear down the caliper will hit on the wing stay(not good) and fitting new calipers would be less hassle than modding the wing stays
Oh and did i say they look good

Brembo better than Wilwood --- but work out the piston area compared to the existing set up if the area is too big an increase you will totally upset the front to rear brake balance.

However do a lttle test first -- (on the hypothetical desserted airfiel test track) take the car up to 70 mph, then brake very hard to 5 mph, repeat twice in quick succession if after 3 such stops in quick succession (ie don't allow time for the brakes to cool) the pedal pressure has increased is still reasonable try a another similar stop if at at this point the pedal pressure required is truly excessive then you need better brakes.


PS don't park the car up with stonking hot brakes as it will warp the discs, allow a couole of miles gentle driving for the brakes to cool.

I think I'd service my calipers first, then do the test above and then make a decision. I assume the Brembos would be second hand and may need sevicing too. Hi Spec do some very reasonably priced Ford replacement, light weight calipers, and they are a British manufacturer....

1) Hi Spec are shit

2) when was the last time being a british manufacturer was ever a good thing?

Thank you for your measured and informative response, Alistair..........

If you search the internet for HiSpec then there are a lot of horror stories out there, mainly about customer service, but also some about quality issues.

e.g. http://boardroom.wscc.co.uk/cgi-bin/ikonboard.cgi?act=ST;f=1;t=49041

As for British made, many things manufactured here are excellent but others definitely aren't.

Ive never heard anyone say "my new hispecs are awesome" without following it up with a string of problems, or 6 months later removing them again. They just seem to be not only of poor quality, but backed up by little or no after sales.

Beyond really expensive items, Im struggling to think of anything Id rther have made in the uk then elsewhere...
