Rear Brakes Lock Up.

[wandrinstar]

A Poster asked about a Mitsu Truck locking rear wheels. It was generally accepted they all did when unladened .Also regarding ABS, do any old hands remember the Warning Poster about ABS, the Thais regarded them as a Miracle cure and you could drive nearly touching the guy in front. So i guess if ABS is any use on Trucks,it must have Rear Load Sensors, to acknowledge the 1000 Kilos of Passengers hanging on the wipers..Or do they lock up the same.?.

ABS come with EBD (electronic brake distribution), replacing the old hydraulic load sensor over rear axle. It disributes brake force between front and rear to avoid any to lock, and then when a wheel locks, ABS is engaged on that wheel.

Exception is Izu/Chev, as they only have one (3 in total) rear sensor, one rearwheel without traction engages ABS on both rear wheels, thus longer braking distance

I read somewhere new izu/chev 4x4 come with only 2 sensors, one front and one rear, which will make braking on slippery surface even longer

Typical GM to go as cheap as possible

On non ABS rally ars, we used to adjust rear hydraulic sensor to provide more rear brake power, to get rear end drifting more easily

I read somewhere new izu/chev 4x4 come with only 2 sensors, one front and one rear, which will make braking on slippery surface even longer

Lower models have 2 sensors, but the new Isuzu/Chev models with stability control have 4 sensors.

Stability control can only work with one sensor for each wheel, ESP needs to know which wheel has reduced traction.

so IZU/Chev saves 500 baht a vehicle on lower spec ABS models, and increase braking distance to produce xx number of mortalities a year. They sure are unbelievable on saving

Big improvements then. I think Thais abuse the benefit intended for extra speed. Personally im not an AIDS Fan , they make nit wits look fast , and predicting breakaways should be part of ones awareness at all times. Our old Spanners Guy just told me Ford sponsored the be careful signs years back. One other point,are Hakka Tires available here, they transformed a Sporting Drive for me back in the World.

all market motorists use tech to go faster. Audi Quattro is wrecked far more often in single vehicle accidents than Audi frontwheeldrive, and it sure isnt due to its reduced traction

I have been driving a 2006Tuna with 16 inchers for a couple of months, and simply had to limit my cruisingspeed to 140 due to poor brakes and crap tyres.

Used a 2010 Vigo on 17 inchers last week on a 3600km roadtrip, and could finally cruise safely at 160 again

[funcat]

..."cruise safely at 160 again"...no comment ...

[wandrinstar]

So there is a good reason for them to spin into the Trees at 30 rather than the 130, caused by the Gizmoes.. Progress is a wonderful thing in the hands of fools.

Sometime back people were throwing money away by putting disc brake sets on the back and replacing the already very adequate drum brakes. The only effective way to prevent rear brake pickup is the factory ABS. Since most of the braking power is the front discs, the back brakes do very little and will indeed lock up without ABS.

A brake bias valve is the key to rear brake lock up. Factory set valve or if any brake enhancement is fitted then a manual valve must be fitted. Been there, done it.

They do go on theses Boffins, as long as you could do a Handbrake Turn and piss the neighbours off at midnight,thats all i wanted rear brakes for at 17..

[culicine]

I note that the new ranger has 300mm+ front disks and twin pistion calipers. How do they compare with the competition? With the other gizmos and unladen, should it provide adequate emergency braking? Or should I load up the back with all these useless leftover sandbags:)

2011 Chev/Isuzu also have 300mm front discs, as will Mazda BT-50 when it officially launches next year.

Hang on to the Sandbags.The nice Design Engineers planned for trucks to carry 10000 Kilos, hence they bounce about when empty. Brakes have never been a prob , just another fashion statement.I do wish they would set Truck Dipped Lights when fully loaded when new.The fact they are too low when empty is the price you should pay for being a truck driver when there are so many nice Cars about, not using 3Litre engines.

Australian Design Rules (based on EU rules) require that vehicles fitted with Xenon headlamps have a load-levelling system (i.e. suspension levelling) or a headlamp levelling system, so that the beam pattern/height is always maintained. ADR's also require that xenon fitted vehicles have headlamp washers (note this is relevant because all of the new trucks are headed for Oz).

Higher end models of all the new pickups (Chev, Isuzu, Ford, Mazda) all feature projectors - but may or may not also include HID xenon bulbs - if they do include xenon's though, they will need auto-levelling to comply (as well as washers).

So we have to wait for all Thai models to be released, but at least there's some hope that auto-levelling will be incuded on some variants..

with ABS/EBD there is no need to load to reduce rearwheel locking. EBD will allow only adequate pressure on rear brakes. Rear brakes have to be large enough to cope with 1 Ton load, but EBD will only allow them sufficient pressure to lock up at same time as front brakes.

Any increase of load will increase braking distance

saying that, pickup gets more comfy with a 200Kg Ninja650R in the back

Ford seem to go cheap in TH on this one, as all TH pictures and spec so far are H4 reflectors. Which I much prefere over non levelling projectors

Whats the story with ride height. I'm curious to know if pickups have aftermarket coilover kits, something similar to that found for regular sedans. Not sure how it would work in leaf spring rears of the pickups:) I like the high riders, but feel in the dry season it would be nice to drop it a few inches. Or is there some other simple system to easily adjust the ride height?

Rear leafs are extremely easy to change ride height, just replace shackles at a few hundre baht

Front coils, new springs

but why drop it at all?

[wandrinstar]

There will still be millions of trucks blinding people unless at the Test they drop a ton weight in the back and set the dip accordingly..50% of my 1250 K a week are done at night and im a bit pissed off with theory.So the beams will be low,so drive within truck design, full of Turnips and in the inside commercial / cruze lanes..

No real reason, just curious if it was possible. My BIL wants to actually increase the ride height on his PJS. Something called "old man" brand or something like that. It seems pretty high to start with.

I'm guessing he wants the Old Man Emu Nitrochargers - if so, good choice They raise the ride height an further 80mm, improve ride, improve handling, and will last practically forever. Make sure he gets the right fitment though - there's a huge amount of variants in the OME's to allow for added weight of tow bars, front winches, bull bars etc, and then even more based on OEM springs and different 3rd party spings - all up about 40 different part numbers for the PJS as memory serves. i.e. they're not user adjustable - each set is factory calibrated for a specific use-case.

He should also look at fitting some poly bushings as well, as per recommendation when fitting the Nitrochargers.

well, reality in TH is, others will blind you

There are driver technicques to reduce the effect of it. They are all based on the fact it takes +30 seconds to regain nightvision after being blinded. So better to be blind looking elsewhere for 3 seconds, than blinded and remain blind for 30 seconds. Where I come from we can be totally alone at the roads in 150kmh for +10 minutes, only with our own lights. Then we meet another vehicle and they have 6 x 8 inchers highbeams. Learn or die

Let your eyes follow the left side of the road, thats where the unlit vehicles and pedestrians appear, and you avoid being blinded

Never look directly at oncoming vehicles, the red lights or black road in front of you are more important

If no way to avoid being blinded, partly close your eyes

Give others no reason to use highbeam when meeting you, do not use fog lights in combo with low/high beam

Reduce all interior lights to a minimum, f-cking japs who dont include AC and stereo lights in dimmer, sometimes miss a proper Euro ride

I have a prob with not being able to dim the dash lights in the Vigo for night driving.

better since late 2008, but still no dimming of centerconsoll functions and the bloody lighter. Far from audi/bmw/benz/volvo

Yep, and l think it is a safety feature, don't understand why it's not standard.

He's talking about a Pajero Sport, not a Vigo

[wandrinstar]

If i was a Vigo Owner id lower it or put a Modesty Skirt on it. That Guy in the Mirror laughing his balls of has just spotted the Shocks..!!! The ones on his 125 Honda Dream are bigger and of better quality. Well they are Chumps now. Three Cheers for Mitsu.
