Slid into a junction tonight

relax carry on

As the title says, I slid into a junction tonight. Bit of brown trousers moment as I almost got smacked by a van.

Coming to a junction near home that I use every day. It had been raining most of the day so road was wet enough. Wasn't driving too fast. Probably 40k. Put my foot on the break to slow down and the break shuddered and didn't slow the car down as normal. Kept my foot on the break hoping it would engage but just kept shuddering. Slid into the junction in a straight line, avoided the van (thankfully) and got the car under control again.

Drove off and tried the breaks again with no issues. Now I'm off to a garage in the morning but is like to know peoples thoughts on what the problem could be with the car. And what did I do wrong.

Thanks.

Sounds like your abs kicked in? It feels like the brake is almost kicking back at you?

40k is fast enough if you were approaching a junction?

Wet road, bit of speed, skid, abs kicks in?

Sounds like the road was quite greasy, ABS engaged and you touched cloth.

Keeping your foot on the brake pedal was your mistake IMO, I find it's much better to lift off the pedal and try to engage braking again.

How hard were you pressing the brake pedal- the shuddering you felt may just have been the ABS working.
You may have unwittingly come upon a bit of a diesel spill of some sort.

Also, have a look at your tyres.

On a serious note hope your ok.

It does sound like ABS and nothing is wrong with the car (apart from perhaps $hitty Chinese tyres with no wet grip, OP what brand and thread depth on the tyres?).

On the letting off the brake, he shouldnt have to or even want to do that with an ABS system though? Thats what the ABS is already doing, letting it off and on manually will interrupt the process. You would let it and on without ABS though, to prevent lockup.

The brake shuddering is the ABS engaging.

There's nothing wrong with the car, you approached the junction too fast given the wet condition of the road, causing you to brake too hard and wheels to lock up.

Try going hard again on your brakes on an empty wet road and you'll see that your brakes will shudder again

I know he shouldnt have to release the brakes as that's effectively what the ABS is doing, however I've found that in a situation like this it's actually easier to regain control of the car by coming off the brakes and then going back on.

ABS is often too agressive for it's own good, I find by going on the brakes the second time ABS won't kick in, as you're over a different patch of tarmac with hopefully a bit more grip.

I've had that same experience DB once when I skidded on a patch of black ice.

Thanks for the replys. Had some idea it might be the abs but not sure. The feeling from the break was quite a hard shuddering.
I thought with ABS in a situation like that you just keep your foot on the break and concentrate on steering the car.

Just checked the tires which look in good order. Never checked the makes before but the two on the front are triangle talon and the back two are infinity info 5.

A quick google doesn't rate them highly. Time for a new set me thinks. Any suggestions? Still dropping into a garage though just to be on the safe side.

Do a search on here and you'll get load so of recommendations for tyres. The first time you experience ABS kicking it can be a bit of a fright if it reacts hard.

Especially if that first experience is in emergency situation.

That's why I think every driver should try it's car is safe environment (like a big empty parking lot or sth).
Accelerate hard, turn hard, make the car skid, try abs, try esp, etc...
It's way better to be familiar with all that before you need to enounter it in emergency situation.

That's what you are meant to do, but many people unfortunately whenever they start feel shuddering from their brake pedal, either keep it as it is, or even release it a bit.
What you are meant to do, is to press the brake pedal as strong as you can.

On slippery surface ABS can kick in even with very little braking force. But if you put more pressure on the brake pedal, you will still increase braking force.

From your description OP I assume you might have not used full possible braking force, because you were surprices by shuddering.

You might give your ABS a try next time, and just floor the brake pedal in some safe place with no other cars around. Fiddle with it for a bit, and see what difference does it make.

And forgot advices that some guys gave you above about releasing the brake pedal and pressing it again. It makes no sense with ABS.

I actually think it's an inadequacy of the driving test they only test for "normal" driving.

It's happened to me a few times (three) driving and hitting black ice, and I'm intending to do a course on a skid pan in the next few months to give me the confidence I know I lack when these things happen. As I've had a couple of experiences of it now, I'm more confident, but I want to learn how better to cope.

It can be very hard to find places to practice stuff like this in to be honest for a lot of people.

Ahaa the good old Ditch finder Triangles, I wouldn't put them on a silage pit, Op if you value your life and car, throw away the 2 front tyres at least and fit some proper non chinese rubber.

If you end up panicking as a result of the abs action, sometimes taking the foot off can help with that?

Certainly helped me, I'd only to deal with steering, got that done, and then braked again and found I was ok

AFAIK controlling skids is only part of driving test in some Scandinavian countries. Anyway - fair play to them, as I think it should be introduced everywhere.

It might be hard, but it's not impossible.
Nothing is impossible to the willing mind.

I spend hundreds of hours training advanced vehicle control, sometimes in really rural places, and sometimes less rural. I got caught few times and had to cope with penalties. Anyway - I think it was worth every minute, every litre petrol I burnt, and every bit of tyre I wore to improve skills, as those skills saved me from good few accidents over the years.

Like I said I'm specifically looking to spend time and money on learning how to control my car in skid situations and I think it's worth every penny.

For a normal driver if you have never engaged ABS it can be a terrible fright.

I was going around a round about in Roscommon in June there. Greasy oul morning it was 7 am. Back end of car went from me as I was going round. Ended up facing traffic half way around. Think I was too fast going in along with the wet road. that was a touching cloth moment alright

Agree

I'd say person who never engaged ABS is not a normal driver, but rather unexperienced driver

This is why people should slow down with their gears, this is the exact kind of thing that makes coasting stupid (not that im saying you were coasting)

The only lesson to take from this is to make sure you have decent tyres fitted.

Slowing down with gears...wtf.

Mechanical pull from switching down gears will sap most of a car's momentum off rather than just clutching and then jamming on the brakes and switching from x gear to 1st when stopped.

I know gears will slow a car down. But it's not going to change the OP's situation. Stopping in emergencies, or going down hill, no matter how much engine braking you utilise you're not going to have enough force to stop the car in good time.

Going slower as you reach the junction is always a good thing, it certainly couldn't hurt.

First thing i learnt when driving was never to rely 100% on my brakes coming up to a junction, plan ahead

Same thing happened me yesterday actually. Was coming out of a town and started accelerating, then realised there was another ramp and hit the breaks only to shudder like mad. Luckily I was only doing around 40mph so slowed to 20 by the time I hit the ramp.

Was probably a tyre fault more than a braking one, sounds like ABS kicked in and you just didn't have good enough tyres to put the braking force down

Goodyear tyres with plenty of thread and properly inflated so can't have been that. I probably should have released the break and pressed it again but it was only a ramp and I was curious to see what was happening.

I had triangle talons on my old car.. You'd be better off with actually triangles!

When you're changing your pants, do the tyres too

+1. I had Triangles on Audi a4 when I bought it. Car never felt right, in wet conditions traction control was constantly kicking in. Changed tyres to Avon car feels great now, traction control only kicks in now if I really push hard.
