My rear brake setup is standard as of 1992, I’m looking at the following disks and pads to replace the originals due to age and wear.

Any thoughts on these as being a good/suitable alternative?

The rear brakes are Ford based.

The pads are the same irregardless of whether the disc is vented or solid.

I've not had any problems with EBC. They do an anti-squeal sticky pad that goes on the back of pads and I would recommend using them. Or Ceratech grease.

What pads do you have up front?

What type of driving do you do?

There is the possibility of unbalancing the braking set up if you fit high performance rears and keep OEM fronts. In everyday driving - ie within legal road driving - it is unlikely to be an issue. If you're 'pressing on' or doing 'track' driving then it may cause you issues.

If you are only doing road driving then can I suggest you look at the EBC Ultimax OEM pads instead. They are pretty dusty if that is an issue for you. Alternatively, get a matching set of front pads. Fit them first and let them bed in, then do the rears. Do a fluid flush / change when you do the rears.

Can't comment on the type of brakes you are looking at...... but as said above my concern would be upsetting the balance of how the car brakes....

I know it's not the same but a I drove a car with trackday tyres on the front, and road tyres on the rear... it was so unbalanced it was dangerous.....I'd imagine something similar would happen under braking.. I could be wrong, but that would be my fear

Hi mk1fan,

Thanks for your reply smile

I have had 4 Pot - Hi Spec up front for many years (an awesome upgrade and have saved my life a couple of times!). Not sure what Colour the pads are, possibly green.

I drive fast road with late breaking... smile and plenty of hills in Wales.. No track days until they build the Circuit for Wales (just up the road from me!) smile

I have lost part of a pad on the rear so they need replacing and thought it best to change the discs while I'm at it (they are still original from 1992).

I could go for Standard solids 11mm and Mintex but thought these maybe a better option.

Should I stick to the standard or go for grooved and green stuff instead of yellow?


Cheers

If you've upgraded the front already then what you posted is fine. Indeed it may 're-balance' the brake set up so take some time to reaquaint yourself with the new braking setup.

Unless you've done it in the last twelve months, I'd still do a fluid flush / change at the same time.

Hi Steve

I see what your saying, the balance has been perfect for my driving style for the last 15 years until I lost part of a rear pad at the end of the summer.

With the change of brake pad technology since 1992 I thought it maybe wise to look at todays options.

Maybe solids and std mintex is best but I do brake hard and late smile

So,


Is it generally best to have a softer brake pad compound on the rear compared to the front?

My preference for brake pads is Ferrodo DS2500, I have also had good experiences with Mintex. I would't go for EBC again.

I am in the process of upgrading my rear discs at the moment, more info here. Will be replacing pads with Ferrodo DS2500 and will be putting the standard callipers back on once they are back from refurbishment.

Hi Mathew

Thanks for the info smile, yes I did have a quick read of your post but I'm not sure our callipers are the same as your Griff is much younger. My Rear callipers cannot take vented discs and as standard were about 11mm thick solids.

So, I'm not sure the upgrade would suit my callipers????

I'm tempted to just purchase the EBC GD280 discs and some standard Mintex (MDB1287) for now.

Having said that, I'm assuming the pad compounds need to be the same front and back or softer on the back. I have Hi-Spec Green Stuff on the front at the moment...

It would be good to confirm how and if pads can be mixed front and back???

Cheers

OP, do beg your pardon, misinformed you there, I've got 273 discs at the rear, not 253 > don't believe your calipers will fit the GD280 discs....

Hi Frank

Funny that, I'm reading the GD280/D280 are the correct diskc for the smaller/early callipers...

Even the Griffith Parts list suggests this, assuming I'm reading it correctly and its correct...

Can anyone else confirm?

Cheers

Noted the new 'width' is 11 mm, so yes, they should fit .......

The rear disc size is either 253mm or 273mm.

Both sizes are available in solid or vented versions.

One caliper and carrier type suits the solid discs, the other the vented discs.

The hub mounting holes locate the caliper and carrier to suit the size of the discs.

My preference would be match brake compounds front and rear but unless they are wildly different in terms of performance I don't think it will matter much. I have mixed Mixtex and Ferrodo before with no issues.

I am not sure on the rear brake specs for early cars vs later ones, I know the fronts where bigger on the 500s but I was under the impression the rears were all the same. This is only an assumption and am ready to stand corrected if anyone knows any different.

Just check what you get.. my mate has just had a similar thing with EBC discs to what I had here...
Make sure they are machined equal (true and central)and that they are balanced... smile
