Brake problems

[kiwiwonder]

I just got my alternator fixed and now when I drive and put my foot on the brake it is as stiff as anything just like if the cruiser is not running and the brake has been pushed in a few times. It is not always stiff though when I am driving. and sometimes it is stiff when I first push it in and then relaxes to where it should be. It is so stiff that I can hardly push it in at all. I'm not sure if it is a vacume problem as since I got my alternator back i noticed my oil preasure is lower. I have a fj77 with a 3b engine, alternator with the vacume pump on the back. An sugestions at what might be wrong? It had been doing this once every two days before I got the alternator rebuilt but I thought it was because my vacume hose was not stiff enough and was collapsing. I have a proper vacume hose now. It does it most of the time now

Sounds like you don't have vacuum at the booster. Were all the hoses reconnected correctly at the vac pumo when you rebuilt the alt?

I'll check again tonight when I get off work. Is there any way that the vacum pump could have been installed wrong on the back of the alternator?

 

[beanz2]

I hear the splines could be stripped on the alternator shaft.

[kiwiwonder]

how do you tell? Pull it apart? can this be fixed, I assume that it would not be anything that the alternator shop would have done

 

[crushers]

if you do not have any vacumm at the pump it WILL be the splines, no doubt about it. pull the alternator, pull the 3 10mm bolts holding pump to the alt. see? told yah...
cheap fix, $1600 C from thelocal dealer. do NOT buy used, might last 6 months might last 2 years but you will be buying new sooner or later...
cheers

Thank freakin god the PO for my BJ42 had to replace the alt and vac pump a couple years ago. The dealer charged him $1900 CAN for the pump

that would be the pump and the alternator, what ends up happening is the splines get torn off both the pump and the alt.
very costly oops. crappy design from Toyota...

Why not just take the hose from the pump to the vacuum reservoir and see if you can feel any vacuum while the engine is running? May have to have somebody rev up the motor to feel the vacuum. There is also an o-ring that seals the pump to the alternator. If this wasn't reinstalled, no vacuum.

that is the test but no vacumm, pull out your wallet...

Not to get to excited yet, I spoke with Arron aka Kiwiwonder and he advised me he has vacume at the pump. He was however cut off on our phone conversation (bad connection), he did mention it was intermitent which is something I have not run into.

As I spoke with Arron, he mentioned the rotor was in tact. I did not get to ask him if the splines were visible on the shaft.

Arron you did mention you could spin the rotor freely, I never did ask was this with the alternator hooked up to the pully. And was it spining on the shaft?????

yeah I got cut off last night, phone died sorry. I get some vacum and the splines seem to be fine. Was running better today. Will test it more

 

[beanz2]

Check that the O-ring between the alternator and the pump was installed correctly. The vacuum reservoir could be rusted and not holding any vacuum too.
