    I have a 1999 Tacoma Sr5 4x4 and I’ve replaced the rear shock absorbers on the truck as-well as the front shocks and springs and the front cv joints too, I’ve also put a new rack and pinion on the car and all new braking system (both front calipers front pads and rotors, rear drums and rear drum shoes as-well as new wheel cylinders) I’ve also replaced the passenger side wheel bearing. But ever time I go to brake and slow down the whole car will violently shake whenever I use the brake normally but then I nearly touch it it’s fine or if I slam in the brakes it won’t shake. It’s getting very violent and not safe to drive. Would anyone have any ideas on what could cause this?

    Possible worn-out carrier bearing?

    Were all the new parts an attempt to solve this or did it start after some new parts?

    Recheck all the parts you replaced maybe you left something loose.

    All the new parts were to attempt to fix this shaking and I’ve gone over everything a million times. I’m not sure if it is the carrier bearing which is original on the truck

    Mine did the same

    my LSPV was bad
    Causing truck to stop with 100% front brake bias

    Did you see the wear difference between drums and front pads?

    Mine: drums 2% wear
    Pads. 70% wear

    did the $45 delete with manual rear brake control valve (jegs)

    I just checked and my carrier bearing is shot, I’m not sure about the brake pads I just redid them and they seam fine, the original shoes were pretty good still but I swapped them anyways and I do know that if I brake using the e brake to test out the rear it does cause the truck to shake aswell while driving and stopping
