I've always heard that carbon brakes don't do well with water splashing on them...

Since there is no brake cooling table, is there a particular technique to work out whether I should be landing with max reverse to limit brake temps? I want to use idle reverse as much as possible but I don’t want the brakes to be amber by the time I push back / reach the runway.

For info: Our fleet DOES NOT have brake fans and the turnaround times vary from 45 minutes to 1 hour.

Any help would be much appreciated.

Carbon brakes used on aircraft such as A320 aircraft can indeed be vulnerable to water splashing. When water comes in contact with hot carbon brakes, it may trigger thermal shock; when this happens it causes carbon material cracking or delaminating which compromises their performance and safety.

As water can splash onto brakes during wet or rainy conditions, being extra cautious to decrease thermal shock risks is key to protecting them from being overburdened with liquid. Here are a few strategies for doing just that.

Taxiing and takeoff: Be wary of large puddles or areas with standing water on the runway; whenever possible, opt for dryer sections when possible.

Landing Technique: After landing, avoid excessive braking until the aircraft has decelerated and its wheels have spun enough to clear away any water accumulation on its brakes. This can be accomplished using gradual brake pressure initially before gradually increasing it as wheels rotate more quickly.

Once on the ground, keep the brakes lightly applied while taxiing so airflow can help cool them down, helping evaporate any residual moisture and keeping your brakes within their safe temperature range.

Is the idea that manual braking keeps brake temps lower compared to Auto Brake just anecdotal or is there anything from Airbus to suggest so?

It’s a common sense. You start using brakes at lower speed, you have lower brakes temp as a result.

Hardly a fair comparison!

The point is if you brake manually within 2 seconds of touch down in the exact same way as the Autobrake, the brake temperatures are going to be exactly the same. There are people who believe that just by pushing a button, you are destined for hotter brakes. When comparing, at least make it a level playing field.

Now I see. I’m saying exactly the same. That’s why I suggest to use manual braking at lower speed (below 100 kts) and not to use autobrake. Looks like you misunderstood me

Jonty, I had a similar experience to you for the best part of 15 years. Then it happened. Where I least expected it. Smaller airports with short runways actually give us better control over managing hot brakes. Ludicrous airport layouts like Barcelona where you can be parked on the far side of the airport only to then have to taxi around the entire perimeter of the airport before you can depart (runway crossings not allowed) are the real culprit. 10 brake applications from 30-10 Kts (our company doesn't allow single engine taxi out) on a 30 degree day without brake fans will give you hot brakes at line up.

If you're landing somewhere long enough to have the luxury of delaying brake application until 70 knots then brake cooling is never going to be an issue anyway. Try landing in 1900m and get back to me.

Sounds like LGA to me. Same technique, except when landing a heavy 321, in which case it's medium autobrakes until the reverser rev up, then autobrakes off until 70kts then feet on the brakes again. Won't keep them under 200C, but under 300C-350C for sure. By the time we deplane 228 people and board up another 228, things will have cooled down nicely.
