I did a quick brake inspection this past weekend and noticed my rotors are looking fairly grooved. I have been using EBC green stuff pads which I am happy with. Just wondering other peoples experiences with vented and dimpled rotors or is this excessive expense for a car that does not do track duty or serious mountains aka Swampers.

Happy thanksgiving to my Canadian friends:

Currently working on a big brake set up for my car using 11.75" ventilated discs and Wilwood dust seal calipers.

The only reason I'm doing it as the drivers on those dash cam programmes you see from Russia have nothing on what I have to put up with driving my C here.
I try to keep a safe distance from the car in front and some idiot always fills it only to slam on their brakes to turn in front of me.

So from my point of view, good brakes aren't an option!

I agree...the standard callipers and rotors in good order and condition will lock the fronts if pushed hard...you can't ask for more than that under normal road conditions plus you Canucks have snow/salt to deal with etc etc

Alan,
I have solid unvented discs on my MGC roadster and they work just fine for the weight of the car. My modified MGC GT (302 Ford) has the Australian DBA drilled and grooved discs with Toyota 4 pot calipers. They are somewhat noisier (due to the grooves) but the advantage seems relatively notional as they are hard to fade on mountain descents - just like the stock brakes. The originators of using the Toyota conversion in the UK did some testing and obtained shorter braking distances. The Toyota pads are significantly larger than the stock Girling items. I fitted the uprated brakes as the V8 gets you up to higher speeds very quickly and you sometimes have to retrieve the situation!
Unless you are planning on brake upgrades due to a shortcoming in the stock system or substantially improved performance, I would just replace with stock items.

Good Luck, Bob Elwin.

3 Pot but to fit you have to weld and redial the mount holes, I have nearly made a set of vented using Wilwood callipers and a one off disc from a manufacture.

Also used EBC and Alloy hubs

Solid Brembos on my 1969. They work great.

Hey guys, Thanks for all the input. I will stick to he standard solid disks and EBC greenstuff pads. Shaun your work always amazes us. Thanks for those great pictures. Clearly that is the ultimate setup. Probably goes with rear disks, Willwood masters and in car brake proportioning valve. We will leave that mod for my fantasy MGC GTS. I do however like the Toyota caliper conversion. For now parts have been ordered. I think Ron Neal said in the second post money spent better elsewhere. My question is how he suggest I spend the money saved????? Endless possibilities when you own a British car. BTW the part number for EBC pads for the MGC is same as Capri pads DP 2291. The holes for the pins need to opened up slightly.

Cheers,

I think if you go for a soft compound that usually brings a more responsive brake for those sudden stops while you lose a little on fade you will get better protection from the cut and dive artists that seem to have taken over the roads smiling smiley

I have run green stuff for a while and run soft stuff in my regular cars as well. Hard compounds tend to work poor till they get some warmth in them.

only really had trouble if i drove the WRX (wifes old car) with a vengeance which despite all the light weight trim and panels would have the brakes smoking and then fading after 15 mins or so of hard hill, country driving so soft is best most of the time. IMHO.

As some one who rode bikes for a decade in my youth, drilling, slots etc help a bit with water clearance, but good brake habits ie clearing the rotors with a dab prior to actually needing them is just as effective,

I realize my advice has started to get boring since i turned 60. What is that??

I would think about a romantic dinner, flowers or some other activity or purchase that your partner can be pleasantly surprised by winking smiley

Be thankful for your understanding spouses, I'm afraid it didn't work for me.
Until our divorce I've been making up for lost time, who needs retirement plans.
