I think the LSPV is a really innovative design by toyota for the time... it was basically an early ABS system. I agree with you that it works and should be used if possible on a stock truck with drums in the rear. I was just trying to answer that guy's specific question why people switch to rotors in the rear. With rotor brakes in the back, the LSPV doesn't function as intended as you need far more pressure for the same stopping power and any lift will change it's total range of motion which throws it off as well. As the system is designed, the rear with drums only sees about 200-300 psi on hard braking, which would give nearly no braking in the rear if you convert to rotor brakes.

I don't have thin skin, just get defensive way to quickly due to military training and PTSD... perhaps I fired off too soon. The guys post didn't seem to me like a "head up, it's 6 years old", seemed more like a sarcastic post. Context is missing so it really doesn't matter.

 

 

You're welcome wallytoo. Someone had to go. Spent nearly 4 years in combat/war zones, so I'm a little messed up to say the least. Thanks for clarifying the post and I've got nothing against you bud.

 

Kelvin, please keep in mind that most posters here don't intend to pop off with an attitude, but there are many (like me) who like to poke fun and are trying to keep things light hearted but also try to heighten awareness when someone didn't notice something or didn't include enough information for us to help. Like when someone says "my truck won't start" and we don't know anything about said truck. I love nothing better than to tell them how to troubleshoot their Kenworth.
don't let any of this turn you off, this is a great forum and far more active and helpful than most.
I would also like to thank you for your service, was that you I saw at Iwo Jima? See, just having fun, but I am serious about thanking you!

 

Certainly is an informative forum. I learned all kinds of stuff I didn't know, like what a "dashpot" is and what it does and all kinds of stuff like that. I'm almost done with my latest project and I think I'll do a whole write up on here with pics. It's a full trail gear build (I rebuilt the whole truck) and I know they sell parts to many many yota fans so I think it will help to see all the kits and how they go on, problems I ran into, etc.

 

Check mine out "Akwheeler's 95 4runner SAS " all trailgear

 

 

Best idea is to keep the LSPV adjusted and working correctly. I will never recommend removing the LSPV.

 

Given the option you would scrap a vehicle if the LSPV was obsolete rather then eliminate it all together

I have never had one that really worked

I guess it comes down to what your used to.

 

I'd buy a new one from Toyota. Only $122.
