Seems like if it's under warranty and the brakes went out, Dodge would be liable to some extent.

He may have had what is called brake fade which is when the fluid overheats. were the brakes on his Horse trailer working? that is the first thing I would find out

He said when he tapped the dreaks they went to the floor, he tryed to pump them to see if he could get anything but they were dead, then started to down shift and started to his the trailer break when were the only things that slowed him down... could have been worse but the trailer break is about the only thing that slowed him down to about 25mph when he rear ended a car

That is why the Emergency brake is cable activated, for situations like your buddys.

Well he tryed to talk to the dealer yesterday and they are still leading him around about "The Actuall Cause of the Problem" so he is tired of waitin on them to give him a response so he went and spoke to his lawer about what can be done to get out of this truck.

The Lawer said he would have to sue the dealership but only to get his down payment back, which was 2,000, and the lawer would cost 6,000 to go to court. But it would get him out of the truck and note, but still stuck with a at fault acc. on his record for the next 3 years (which will make his insurance go up)... So he is going to go to the dealership today and try to scare them into just taking the truck back or trade for another one ,Well thats about it right now

Brake fade has nothing to do with the brake fluid (big rigs don't even have brake fluid). It is when the pads and rotors or shoes and drums get so hot that they cannot create enough friction to be effective. This is why big rigs (and newer CTDs) have engine brakes of some kind.

Ever sit at the bottom of a hill (Grapevine, Cabbage Hill, Donner Pass, etc) at some point you'll probably see a truck come screaming down the hill at the bottom. The engine brake can only do so much then, if speed builds up the friction bakes are used and if they are used to much they heat up and away you go...:eek:

Sue them to cover court and lawyer fees. Bieng that the truck is so new this is a safety issue and should be paid directly by Chrysler. Know your laws people and don't be afraid of intimidation.

Well he spoke to his lawer and since they sold the truck to him as USED he can only try and sue the dealer, if it were still NEW then it would go threw Chrysler.... Now this is what he told me that his lawer said, so i dont know the law for which one he can actually do without me trying to call lawer's and what not...

I was taught in school that a cause of brake fade is when the brake fluid boils which causes a soft spongy pedal since the fluid may be in a vapor state
I have been ASE certified in brakes since 1992 your answer is also correct. I do not know what the big rigs use
I have some military trailers here that are air over hydraulic which use both air and brake fluid

The reduction of friction termed brake fade is caused when the temperature reaches the "kneepoint" on the temperature-friction curve. [All brake lining is cured under mechanical pressure following a heating & cooling curve, heating the friction material up to 450°F to "cure" (cross-link) the phenolic resin thermoset polymers: There is no melting of the binding resins, because phenolic resins are thermoset, not thermoplastic] In this form of fade, the brake pedal feels firm but there is reduced stopping ability. Fade can also be caused by the brake fluid boiling, with attendant release of compressible gases. In this type of fade, the brake pedal feels "spongy". This condition is worsened when there are contaminants in the fluid, such as water, which most types of brake fluids are prone to absorbing to varying degrees. For this reason brake fluid replacement is standard maintenance

i was out in virgina or wv with a full load out on 611 and 69 or 79 i think with all the s turns and grades doing 5 mph for a couple hours. I just installed new pads and I do have trailer brakes also that work. But as explained above, u heat up your brakes and brake pedal feels spongy and barely works. Its just overheated.
