Hi, just changed the auxiliary brake pump(the one one that is on the back over the rear driver side shock)on my 2001 Tacoma but now the pedal goes to the floor she stops but not like before, the shop told me its the brkae pump ,but I dont think so since it stopped just fine before I changed the rear pump.I just changed because its was leaking slightly. any help?

 

you could try the correct sub-forum for your truck, as the '86-'95 trucks do not have that feature.
